Many years ago, CVA had a Spanish made Maslin lock. I put one on a pistol I made some 35 years ago. As you say, not a real high quality lock but a reliable sparker. There may have been some other makers using the "Maslin" name, but I don't know of any.

Edit: I believe Russ Hamm also made a "Maslin" lock around the same time.
Russ Hamm made a Maslin lock beginning in the 1960's. The moulds were paid for by
Bill Large who furnished the antique lock they were made from. The man that handled
that transaction was known for being indifferent to who got what and "exclusive"contracts
meant little to him. "Doc" Carlson that owned Upper Missouri Trading Post told me he saw
items that he paid for in Dixie's catalog before he got any of them. Dixie was NOT complicit
in this bit of poor business practices.
The Maslins Hamm Marketed were not any attempt to make a quality lock available and I
rebuilt a lot of them and marked them as "Roller Rebuild". Hamm told me I was crazy to
take the time I did in making these parts.The cast parts became available to one and all when
Bill Large told the foundry that produced them that they were "Public Domain"items for
anyone who wanted to use them. All components,internal and external were made form the
original lock Bill furnished.
These parts are still available as far as I know from Jerry DeVaudreuil in Wooster,Ohio,
1-330-234-4500. He has no E mail.
