Looks fine Dave
I want to mod it into an "ugly" (You're welcome Dominic ) SAL Q3:
But I'll need to move the front dome, make/buy a new smoke box door, move the air pumps, relocate the headlight, and make/buy new air reservoirs just to get it close to appearing like a Q3.
I recently built a Vanderbilt tender, currently behind a SAL 4-6-0:
I plan on swapping the 2 tenders, their Ten-Wheelers never used the Vanderbilt style tenders.
I have a pencil torch, it's just a matter of, finding/making the parts and...do I want to take on another project or simply do a re-paint?
The Q3 was the main 2-8-2 Seaboard had on their roster, 117 out of about 170 Mikes were Q3 class. The Q3 and Q1 (USRA) were very close dimensionally, at least enough that, given all the other liberties the O scale makers take, the conversion should look fine.
If I ever want a Seaboard Q3 Mike this is probably my best chance of "getting" one as there's not a manufacturer out there willing to build one, given the limited number of Seaboard Air Line fans in the crowd.
