Since this thread seems to have diverted from Seamasters to USPS gripes I would like to get back on topic.
I just acquired a Seamaster 120 which is built up to the point of needing paint. It is covered and primed. After a long look it seems to me it would make a great twin using a pair of OS 90 FS's I have. Does anyone have any experience with something like this? I imagine it would be very much like an enlarged Sea Twin.
