Stock49,
I sure appreciate your persistance in this matter! I have been having some "firewall" problems posting.

That explaination makes good sense if an error by the code stamper is taken into condsideration, which is certainly not out of the question.

I sure thought it was a few years newer than that and hoped for a 250, but that's OK.

Thanks---DAC
