Re: What's it worth
Hawes SA revolvers were made by J.P. Sauer and are of good quality. I don't recall a .25 pistol marketed by Hawes, but in the general pre-'68 market, many were imported by a number of companies. There is near zero collector interest and few are worth more than shooter value. At best, and if the gun is in good condition and fully functional, I think $175-200 would be about tops.
