PW-5 pewter miniature for sale

I have a Polish Technika / Aerotechnika Collection cast miniature of
PW-5 glider w/ a wingspan of about 3 inches if anyone is interested.
It is in the original dark blue box w/ black foam insert.and clear
cellophane window on top. It was my son's. He was an avid PW-5 pilot.
I have no idea what it cost originally, but am thinking of asking
about 10 bucks for it and that should cover my postage, etc..if you
live outside, US, I'd need more for postage. I hate the idea of
selling it at a garage sale to someone who has no idea what it is.
Thanks,

if you email pls put "glider" in subject line, I get a lot of email.
