Ed Schlief, of ABS, rest his soul, introduced me to Sealskin thru his biz (ABS).
he would have native AK make the squares..run a stitch across one side of the 2"x2" square and that made it a Manufactured product, which at that time was adequate for peddling by a 3rd party.
Over time, he found none of the Native AK willing to set up to even buy a sewing machine to do the "Producing" and he gave up trying to peddle it.
I think...THINK, there is a lot of mis-information on what is or is NOT legal on sealskin as in coats, etc.
Once, if it was manufactured by a native AK enterprise, it was legal... the coats in the USA were likely "grandfathered" but that is an assumption, not a known fact.
I covet what of it I got from ABS as it is the best material I've found, but... there are many ways to skin the cat or the shelf as it were!
