George Gibbs .577 P56?

I have just obtained a very tidy .577 rifle by George Gibbs, 29 Corn Street, Bristol. It is essentially a P56 but has a wedge fastened fore-end instead of barrel bands. I assume it was made as a Volunteer rifle but I would like to know more if anyone can enlighten me. The woodwork is very good with a nice finish and the barrel has some original blue fading to brown. The bore is as perfect as I have ever seen on a rifle of this age, bright and sharp rifling right to the muzzle. The number 270 is engraved on the butt plate tang.

What a splendid-looking rifle. I think you will find a lot of expertise on this and similar types at the following address

which is also probably the best place to make contact with other percussion rifle shooters in NZ.
