Hello Browning companions, Waiting for parts for a 1905 model being restored (top of the pic), I decided to tackle my 1903 (bottom of the pic). I thought I had all the parts but, bad surprise. When I pulled the buttstock, the action spring tube was missing. I am going to make a new one. I source a half inch steel tube with a 0,035" wall like the original. I want to do a faithful restoration but the problem I have encountered is how to extract the broken part that is brazed inside the receiver tang in other to re thread like it was originally. Any suggestions, it seems to me I saw a Art’s gun shop video on that subject but I can’t find it. Thank for your help.
