Old Ball collectors? Box of 1 dozen Wilson custom made F-85 balls - $200.

[hesitantly]

I have for sale, an old box of balls, the source of which I do not remember.  They are labeled "Wilson" and "Custom Made".  I contacted Wilson and they claimed they never made a ball called the "F-85".  I'm sure that is probably correct, so my deduction is that these balls were custom made by them (like today's 'logo' balls) in the 60's or 70's, for some company related to the Oldsmobile automobile; their base model car platform was called "F-85".  The balls are unused, and in the original box, and sleeve wrappings.  I have no clue what they might be worth to someone else, but I figure they're worth four boxes of new Z Stars, for me to play with - hence the $200 price (includes shipping).

The F-85 name on the ball has a little outline of a rocket (Oldsmobile's logo, at the time) after it. The other side has "vulcanized".

Be the only one on your block...or on earth?...to have these in your collection!
