I'm sorry, I sold the faceplate (I think it was actually the rarer 12" = 300mm version) to a guy in the LA area. I also had an FP1 horizontal arm but traded it for some Studer grinder bits. Only thing I have left from my MT4 stuff is this:
Schraubstockflansch MK4 Teilkopf Deckel Teilapparat / Vise base dividing head | eBay
If someone here wants it, let me know and I'll pull it off Ebay and offer you a better price.
Thank you for the offer, I will pass.
