I'm looking to buy the pantograph/insulator assemblies from the Arnold GG1 for a project I'm working on. I'm looking for both pantograph designs — the two-spring version with the copper pickup shoe, and the single-spring all-wire version with the thinner plated pickup shoe. The plastic insulator casing style doesn't matter as long as it is one of the American prototype designs with horizontal bars connecting the insulators. If anyone has those parts or full GG1s they are willing to part with, please let me know. Thanks.
