I would contact the seller on this fairly recently expired gunbroker auction... looks like the piece didn't sell, and the price is good.
Will be pleased to pay $100 finders fee for any information leading to the successful purchase of any Lancaster pistol. You younger members know your way round the Internet much better than me so here is an opportunity to make some easy cash.
The Lancaster was a multi barreled handgun ( two or four barrels ) in rather large calibers which saw limited use by British Officers before the introduction of smokeless powder and reliable large bore semi auto handguns, notably the Colt 1911 .45 and Webley .455 semi auto.
Peace through superior firepower
I'll assume it's okay to be outside of Canada? Or does it have to be within our borders?
Also working condition too I'm assuming?
thats not the 2 or 4 barrel one he's looking for. just a target pistol.
