Do you get this sort of "inaccurate marketing" in CanadaJim? I always encourage collectors to tune into Milsurps, get a pot of coffee on, then study the huge volume of freely and generously given information on here, before they part with hard cash.
I have a similar project to yours waiting in the wings Jim, closely based on a Vietnam era chop mod special. Probably get it underway in the new year.
