The PSC No. 70 was imported in the early 1980s (iirc) while the OMI S scale engine was imported in 1990. Two different companies and a growing awareness of how important accuracy is to the modelers in the interim of time. (In fact, OMI seems to have sacrificed quality of craftsmanship in favor of accuracy and detail). I have examples of nearly every S scale C&S model they imported - EXCEPT 74 and a couple of the moguls. Some twenty of them. I've found the OMI C&S engines to be fairly accurate tho not perfect. Knowing this I offer to John the use of my model. I would not have, Otherwise!

That being said this is how the 1/64th tender stacks up to George Lundberg's sketches to determine 537's capacities - before the oil bunker was installed.

Length of tank = 16'-3" (Lundberg's sketch 52")
O-A width of tank = 87.5" scale. (Lundberg's sketch 87")
Height of tank = 40" (Lundberg's sketch 44")
Bunker width (Between water wings ) = 52" scale (Lundberg's sketch 52")
TOR to top of frame deck = 38.5" (Lundberg's sketch 37")
Width of water wings approx 18" (Lundberg's sketch na)
Height of oil bunker above tank deck = 20" (Lundberg's sketch na")
Length of oil bunker = 11' - 11" (Lundberg's sketch na")
Width of oil bunker = 83.75" (Lundberg's sketch na")
BO tank to BO oil Bunker = 50" (Lundberg's sketch na")
Length of frame over sills = 19' - 5.5" (Lundberg's sketch na")
Width of frame over bands = 8' (Lundberg's sketch na")

There is nothing like a 3D object in your hand to understand how something is put together. PSC - Iron Horse Models - isn't known to be very accurate with C&S engines. It's not so hard to replicate a 3D, 12" to the foot scale K-36 but the C&S engines are mostly memory! So. I would not recommend John rely on a little Sn3 model as his sole source of info.

But of course if some "expert" knows better, I'll just not bother...
