How can these rifles be dated?
Am I right in assuming that if the patent for the magazine on my rifle is from 1900, and my rifle is use #30, then was my rifle most likely built in 1900?

I bet there is as much interest in Lee Speeds as Mannlichers, but seems like Mausers are way more popular. Probably due to rarity.
BTW, how many Lee Speed sporters were made?
