Gunbroker has one 331 listed Auction # 240750969 The seller did not list it by model number and that makes it more difficult to search for.

Also has a two 431 listed Auction # 240663259 Auction # 239797028

Our family has a bucket load of each model. Biggest difference is lock versus no lock.

I also use the website ebang.com to search for it, I searched for 32 Mag and it appeared. Also I use variations .32 mag, 32H&R, 32 h&R magnum, and I will get different results.
