HO Long Island G53sd4-6-0 Backhead

[Sumpter250]

The G-53sd 4-6-0's ( #141-146 ) were Brooks built engines. The G-5s 4-6-0's( #20-50 ) were Pennsy built. The 35 and the 39 have, according to the references I have access to, were preserved. One of them is at the LIRR museum at Riverhead, L.I., N.Y.
I have no record, or reference to a G-53sa. I do have a listing for a G-53sc ( # 137-140 ) Schenectady built.
The G-53 ( #123-127 ) were camelbacks.
These are all the LIRR 4-6-0's That I know of.
I do not recall seeing any photos, or drawings of any of the backheads - - - just finished checking my card file of MR, RMC, RRM magazines, and no reference to any of the G-53's. No luck with MR Cyclopedia, Steam Locomotives, or my two books on the LIRR.
My Westside Brass Pennsy G5 ( HO ), has, you guessed it ! only a motor inside the cab
At this point, I'll have to wish you luck, finding the information you're looking for.

I do remember the G5, on the head end of the "Cannonball Express", that ran out to Montauk Point.
