I occasionally rescue old, neglected Wingmasters. I take them in, clean them up, give them a home where they are loved.
You can't go wrong with an old Wingmaster. Around here, the non-magnum guns (2 3/4" only) bring very little money. But, I rarely have need for 3" regardless, so I grab them when they show up.
Normally smooth as silk and in need of very little besides a good scrubbing. Might want to replace the magazine spring.
Pick up an extra barrel and have it cut down if you can't find the length you want. There's tons of them out there so finding an extra isn't really a problem. Just might take a bit of patience.
