Hi folks,
New member on the forum, and looking forward to learning as much as I can.

For the moment though, I have acquired a HAMMERLI Single air pistol, 177 Cal, with a 102mm; (4") barrel.
I would hope to shoot 10 metre ISSF air with it, and if I can make progress, then upgrade to a more appropriate pistol.

I know nothing about these, and was wondering if someone could give me an idea of the year of mfg from the serial number, which is: #421**.
Are these quality pistols (I know they are decades old), and any idea of their value?

Thanks in advance for any help you may be able to provide!

Mike
