Pictures are worth thousands of words. You bought an old '50s vintage J-frame attributable to an FBI agent, and it's in the original box? Hard to say what would be "too much" for that one! Congratulations and eagerly awaiting your pix.

PS Pix came through while I was typing. It looks like you got a really nice one. Again about what you paid for it, I don't know, but it was probably worth it... whatever it was!
