Norm, here are some ver ruff number for you look over...
From 1921 through 1934 there were around 110,000 1899/99's made. I have a few over 500 rifles in my data, Within that 500 I have the following:
22HP = 14 ea (6 are in Australia or Canada)
250 = 8 ea
30-30 = 9 ea
303 = 6 ea
300 = 5 ea.
I only have one in the last 3 years of data.
Not uncommon for the barrel to be a take down.
Sampling is a little squid from specifically hunting data on E's in past years..
