Frank, I seem to remember "BOMB" is an Sherman III/M4A2, but I am sure there are a few threads about it here on MLU. From what I have seen with an M10 restoration, parts for the twin diesels are still available from Detroit Diesel, as long as you are able to salvage the parts used to combine the two to one drive shaft....which I think is unique to the Sherman/M10 (?)
What about all the SECO T16's?....have they all gone, or could there be one left that was just not good enough to get running again.....but good enough for a monument?
