Both of mine are undrilled.
Interestingly the BSA contract is stated as being for 2000 No8s, the No8s at the auction were from s/n DA101 though to DA1126, in every lot of 100 s/n eg 100-199 there were 20 to 30 rifles in that s/n range except DA1126 which was on its own & there was none with a higher serial number, this would leave about 1000 No8s unaccounted for??
