I'm working with Sasa Distephano to revise his U-Boat railings line and we're looking for accurate dimensions. Years ago, a curator at the museum measured them for me, but I can't find them, he's deceased, and I haven't heard back from the museum. I've seen .6 to .7mm (thicker ones), and .4mm for the thinner ones. As this will be for a "premium" edition we'd like to get them right. Any help greatly appreciated! Scott
