Thanks, Rich,
The moisture sensitivity should not be an issue, since I am looking for fakes, (i.e. Mycarta, Corian, etc.). It is that there are simply no makers out there doing these as nice synthetic reproductions. Still looking for a set that don't look like they came off a toy.
If you want the most authentic period gun leather out there, there is nobody better than Rick Bachman, IMHO.
I have owned Bachman rigs for over 30 years and nobody comes as close to replicating the feel, look and quality of the original rigs. He's not cheap, but the product you receive is outstanding.
