Bostitch Stanley Model N95RHN Industrial Round Head Stick Framing

I seen this for free at a garage sale, looked at the guy, and he said “ yeah, free…all it needs is an O ring.” So I took it. I did not test it any, just took some pics and posting it here. May need more, or less, than a ring. Selling as is, for repair, assuming the guy was telling the truth and didn’t just give me a perfect tool. I will ship it ground from Alaska, which takes about 3 weeks. Let me know what my free find is worth to you in the ‘make offer’ section.
