Thanks Lakey, appreciated once again. I will look out for the book.
Finally, you mention:
If you want a No.1 Bore "full powered" Improved model D. The one you want would be an Standard Ordinary Pattern 43.5" Straight hand Stock model with a serial number between 65000 and 80000. these serial numbers are only approximate, however within these ranges you would be 98% sure of getting a rifle produced during the 1914 to 1918 period.
Was the pistol stock not a standard feature (option?) then?
Don't have one for sale do you?!!!
