My dad bought this for my 6th birthday in 1946 at a hock shop for $10.00 then paid a gunsmith to cut the chamber to use the 3 inch shells instead of the 21/2 inch. It had peoples initials cut deep in the wood it took me almost 2 weeks to sand them all out by hand. I don't know what model it is. I had it chrome plated in 1961.
I still have it after 64 years.
