Turtlebacks progress so far

[Walter Plummer]

Hello all. Here is pictures of the vises cleaned up. We are missing pieces but have one of each to use as a pattern. We sent these off to an Amish foundry that was recommended to us. An oddity we found is that the nut and garter for one vise are made of bronze. My partner in this restoration talked to someone who had bought and sold 250 of these vises and he said none had any bronze parts. Pattern makers repair maybe? Lead time on the parts is 6-8 weeks. Does anyone know the original factory color?

Thanks for looking. Comments, advise, etc. welcome.
