I know your pistol thread is almost a year old but I found out some info about it. it appears to have been made In 1916 and only 2114 were made. Your pistol might be worth a lot of money.
Good Luck
thanks for the pics on the shackle reloc brackets. Did you notice any lift differences after install? I am hoping for a gain in lift not a loss. even 1/2" would be fine.
