Great looking...Could you please share a link?
I am originally from (then communist) Czechoslovakia. Escaped 1986 and arrived to the US in 1987. I was able to get one of those old service pre-B CZ 75s from Buds for only $299 and had it re-finished. Was VERY lucky - my pistol was made in 1987 - the year I arrived to the U.S. I think that these grips would look great on it.
I got these grips from here:
http://www.marschalgrips.com/cz75_82-thin/thincz75-82.html They are the "thin grips" for the CZ-75, with red finish. As I said in the above post, I also asked him to add the star from his Tokarev/Makarov grips.
Be prepared to wait 12 weeks or more, and he is a one man show, so he can be slow to answer email's or it may take a few tries to get him to answer.
Great find on your 1987 Pre-B. I'd love to find a 1983, the year my Ukrainian wife was born.
