Thoughts on a Philadelphia Centennial Exposition 45-70 draw set...... 

 

Here's an interesting item that will be of interest to the cartridge collector, as well as the Springfield Trapdoor enthusiast, US history buffs in general, and those who are looking for the $2 garage sale find that will virtually guarantee you an appearance on the Antiques Road Show. In 1876, the US Centennial Exposition was held in Philadelphia. One of the many exhibits at the exposition consisted of a working display of cartridge-making machinery from the Frankford Arsenal, which was used to demonstrate the processes involved in manufacturing ammunition. The cartridge cases that were produced were given away as souvenirs to the visitors at the exposition, but, surprisingly, few seem to have survived. These souvenirs consisted of special inert Benet-primed copper .45-70 ball (2.1") and blank (1.6") cartridge cases with a unique 1776  USC  1876  headstamp, as well as multi-piece draw sets, similar to the one pictured, showing the various stages in the production of the cartridge case. As originally produced, it has been suggested that these draw sets consisted of 16 pieces, as shown in this illustration taken from Robert Buttweiler's Collector's Ammunition auction catalog, Vol. X, Number 1, lot 86 (1994), to which I have added numbers to the various pieces. The description from the auction catalog for Lot #86, while difficult to read, is also shown below, and describes this an the only known complete set among the five other known sets. Items 1 through 5 show the transformation from a flat copper disk (item 1) through 4 early stages (or draws) in the production of the case. The set also has three pieces intended for making blank cartridges (items 6, 7 and 8) and three for making ball cartridges (items 9, 10 and 11). Of these, the pieces which have been through the rimming process (items 7, 8, 10, and 11) have the special exposition headstamp. Items 12 through 15 show the stages in making the Benet cup, which fits inside the finished case, and is held in place by low grooves on either side of the case. Item 16 is a 405 grain grooved lead bullet, which was used for both rifle and carbine cartridges at the time; the 500 grain bullet did not become the standard for rifles until January of 1882. That the set in the top picture has only 11 items would lead one to conclude that it is missing five of its original pieces. I numbered the pieces in top picture to correspond with the matching pieces in the auction picture. Obvious from a comparison between the pictures is that the top set appears to be missing items 5, 6, 7, 8, 10, and 16; six pieces rather than the five that would be expected (16-11=5). The discrepancy is caused by the extra-long (2.610") piece with the uneven mouth labeled '?' in the top picture (the second item in from the top right) that is not in the auction picture. The presence of this 'non-standard' piece leads me to believe that either the auction set is incomplete and should have had 17 or more pieces, or, more likely, that these draw sets were not so consistent as to be able to make a blanket statement regarding what comprises the 'complete' set. Any comments or reactions to my thoughts here would be appreciated.

An interesting thick-rim cartridge.......

 

Looking like just one more of the many variations of the French thick-rim cartridge, this is actually a 11mm Bachmann-primed example, recognizable by its characteristic irregular-edged flat 'disc' primer and its blunt nose lead man-stopper-style bullet. The thick-rim family of cartridges was intended for use in Lefeauchaux and other pin-fire revolvers that had been converted to centerfire. In the process of the conversion, the straight chambers of the cylinders of these revolvers were cut to accept the rims of the centerfire cartridges; the purpose of the extra-thick rim was to completely cover and seal the holes around the perimeter of the cylinder intended for the pins of the original pinfire cartridges to pass through..

An unusual Frankford Arsenal reloading accessory....

The Gill priming tool that is included in the set of Frankford Arsenal reloading tools shown on my picture page last month, in addition to being used for de-priming and re-priming  the .45 Colt, .45-55, 45-70, and .45-80 cartridges, was also used with the 20 gauge shell that was produced for the Springfield Model 1881 shotgun. Converting the tool for this purpose requires a sleeve (the silver, slotted piece in the top left of this picture) to be slipped onto the spindle to hold the shell in place. This  priming tool is marked 'U.S.' and 'O.M.L.', the initials of ordnance inspector Major Ormond Mitchell Lissak; in addition, the three major parts of tool are marked with assembly number 155. The sleeve has no markings, and could easily be overlooked as a Frankford Arsenal accoutrement. The following pictures demonstrate the priming process.

In the picture on the left, the sleeve is in place on the spindle, which is installed on the tool with the de-priming pin positioned to remove the primer. The setter screw (the knob-like part in the top right of the picture) has been backed out to allow the old primer to be pushed out of the shell. In the picture on the right, the shell is in place on the spindle, ready to be de-primed with a squeeze of the handles of the tool.

 The left picture shows the de-primed shell, the primer still partially in place in its pocket, but easily flipped out of the way with a fingernail. On the right, the spindle is reversed for re-priming the shell. The setter screw has been screwed all the way in so that its concave end is in position to push the new primer in place in the shell.

.

The picture on the left shows the shell in position on the spindle for re-priming, and the primer has been partially pushed in place. The right picture shows the head of the shell before and after the re-priming process. The headstamp indicates that this shell was made at the Frankford Arsenal in October of 1884.

Shown below is an illustration taken from the Reports of the Chief of Ordnance for 1882, showing the components of the Frankford Arsenal shotshell reloading set, and the May 16, 1882 patent drawing for the Gill priming tool. The sleeve is shown in both.
