thought i would toss this up for any ideas. not too many people know much about these as they weren't available to the public, only a limited run were produced for sale only to texaco corporate employees (or at least thats what i was told by the corp. employee who acquired these for me in 97).i was offered $500 for one about 10 yrs ago by a pump/parts vendor who has since passed away. i know the market has fluctuated a bunch in the past few years & am curious what these might be worth today. these are unopened, & in the original packaging. thanks in advance for any help you might provide!
