Mike,
how did you come up with 1889? I did not see a date or serial number.

H&H will tell you what the book says if you call. I tend to agree but it weighs over 10 lbs so it is possible it was an original Nitro gun. Holland retailed quite a few rifles in the early cordite era that they claim could shoot anything from a 365 gr to a 480 gr bullet in the same spot. One of out members has one of these rifle that weighs just over 8lbs yet it carries original full boat cordite proof marks. It has seen very little use yet has a shattered stock. Hard to say how it happened but it does make you wonder.
