It is a very cheap Brazilian copy of a USA S&W "J" frame. The GCA of 1968 stopped their importation.
New they sold for about $30.00 in the mid 1960's, which is about $180.00 in today's inflated dollars.

You can likely realize between $50.00 and $125.00 in a private sale, for a .32 cal., today; depending on the actual quality of your particular gun. Some, that I examined when they were being imported, were rather rough, internally.
