Anyone (looking at you PRR fans) know what truck this is?

According to my invoice from Bowser, this is a 70T AAR truck. I never heard of such a truck. The truck is included with Bowser's GLa 2 bay hopper. The few PRR websites that I found with truck information report that the Bowser HO and N scale GLa included 2D-F2 trucks, sort of a home brand 50T Bettendorf:
"2D-F8 PRR Type w/ coil spring Bowser 74277 Shipped w/ F30, GS, GLa kits" from

So, is this the PRR 50T, or an AAR 70T?
