Hi Lance, thanks for the pics!
Steele's is actually pretty scarce, but for whatever reason (we can't figure -- we think it's a very cool game) it's not a high-demand item even among game collectors. We've seen only three playing boards (including the one in Mark's book) in all our years of collecting, but we got ours (missing most or all of the parts, and not for sale, sorry) for $28. and $13. in on-line sales/auctions.
The board (shown below) and dice are really all you need to play the game, but if you're not a "game guy" per se and want to part with the playing pieces for a reasonably low price, IM us here or contact us at our own Forum. Y'know, you coulda just followed the links on our page and asked there too -- Mark Cooper is a member of our Forum as well as this one.
Ah, forgot to add -- except for the board, of course, your set of parts looks close to complete, although we think there should be at least twelve (probably thirteen) coin/marker pieces.
