I have been searching for a nice, original condition, Voit Swimaster Titan II MR-12 reg ever since I laid my baby blues on Karl's non-mag example. The Titan II MR-12 was a short production run of the original MR-12 that had just been approved by the USN. Voit changed the name over to MR-12, and continued to produce the Titan II as a separate model with the Trieste first stage combination.
Anyway, a great big thanks to Russ, "Mistral", who answered my VDH inquiry for the reg. Not only was Russ awesome to deal with, the reg was in better shape than he described.
I am planning on creating a historical piece that outlines the evloutionary changes of the Voit Swimaster MR-12 throughout its production run. This will be in the same fashion as the work compiled by Allan on the USD DH regs.
You will notice that Voit used the two tone finish on the second stage, much like many of the DH models. Captain Tucker, can you verify as to whether your example hs the same finish?
