My wife had this model 36 when we were married 28 years ago. Trying to find an approximate value for it. Is in good condition, with original wood grips. Fired very little.
Just kidding. Welcome to the forum. A picture would help, but I've seen Model 36's in the condition you describe at shows around here for sale in the $ 400s range lately.
Age and condition are everything. I don't know what "good" means to you.
If it has diamond stocks and the finish is 95% or better, the price might be a little higher than our friend Absalom quoted. But he's in the ball park, especially if it is a post-1966 gun.
Explanation added: the flat latch went away in c. 1966; the diamond stocks disappeared in c. 1968.
