This aluminum nock is big, I mean, really big. For comparison, the smaller aluminum nock with it has a 5/16" inner diameter, whereas the larger one is 5/8".Was this for real? Was it a promo item from the manufacturer?
Or for a heavy crossbow
Have no idea. I'm bettin' it would make a good "bow-themed" back scratcher, though. 🤠
A real mystery Ira. Could be custom made for a bowyer experimenting with a heavier bow not necessarily a 200 pounder.
I don't recall seeing any information on 200 pound bows being made in the early 1900s, which is when that type of nock was used. Most hunting bows were in the 50-80 pound range and some were a bit heavier, but not up to 200 lbs.
Looking through some old catalogs from the 1930s and 40s, bow tips, as they were correctly called back then, came in 3/8", 7/16" and 1/2". Didn't see any 5/8". So, I still wonder if that large one was specially made either for a very heavy bow or as an advertisement for the maker.
It doesn't seem string friendly like the smaller one.
Oh I’m sure it’s real as there are longbows still being made today with well over 200# draw weights.
With some normal sized nocks.
Here it is with a 5/8" dowel.
