Re: Antique book on bullet molds and powder shot measure.
I seem to recall seeing a combination mould, screwdriver and barrel wrench like that in the Dixie Gun Works catalog long ago.
I don't have a DGW catalog, but that company is online. A little searching of their website might find it.
In the old days, moulds were marked not with the ball diameter but with the number of balls per pound.
Thus, a mould that produced a 20-gauge ball would have 62 marked on it.
If I read your post correctly, you're puzzled by these markings. The "balls per pound" makes sense of it.
75 balls of .395 inch would equal about one pound.
16 balls of .672 diameter would equal about one pound.
However, about 99 balls of .360 inch diameter would weigh one pound. Your mould is slightly larger, at .363, so it doesn't make sense. It should come in at about 95. I thought perhaps that you misread the 10 and it was actually 100, but even that figure would be incorrect.
So, I'm stumped on the 10-.363 marking.
Dixie Gun Works may have books on antique bullet moulds and accessories. It would be a good site to start.
As to value, go to Ebay, *********.com or Auction Arms and see if a mould similar or identical to yours is in there. I know I've seen such things, on occasion, on Ebay. It's difficult to place a value on such thing, by and large, because it brings what people will pay. Sounds simple, but it's true.
Antique moulds bearing the names of famous gunmakers such as Colt, Winchester, Sharps, etc. can bring up to a few hundred dollars, but it would have to be an uncommon caliber and in like-new condition.
I'd suggest you check out Ebay, search "mold, mould, bullet" and see what prices are going.
If nothing else, contact Dixie Gun Works and see if they'd be interested in purchasing it. They used to buy old, rare guns and accessories, I think they still do.
Hope this helps.
