My great-grandfather was the police chief in New Westminster, near Vancouver, Canada, in 1892 when he investigated a murder. I'm assembling a family letter about the case. The murder weapon was never found, but the bullet was a .38, possibly from a Colt and the gun was said to be "old" at the time. The man he arrested and who was later convicted of the crime had paper-wrapped cartridges for the weapon and caps to fire them. Does anybody know what model of gun this was, and where I might find a photo?
