To add to the confusion on PRR's trucks, please note that there were multiple "Crown" trucks, that were swapped for original arch bars, that include the:
2D-F2 50-ton "Crown" found on classes: FM, GLA, GLB, GLC, GP, GPA, GR, GRA, GS, GSA, GSC, GSD, GSX, H22, XL, XLA, X23, X24, X25, X25A, X28A, and X29
2E-F2 70-ton "Crown" found on: F25, F25B, G22, G22A, H21A, H21B, H25, H22A, FN, and FNA
A variation on this, with greater spring travel:
2E-F2 70-ton "Crown" found on: G21, G22, G22A, H21B, H22A, and H30
These last two are what I think the Bowser Crown truck most resembles. The Railworks brass Crown truck looks more like the last of these, the:
2F-F1 100-ton (or 95-ton, in other sources) "Crown" truck found on classes F25A, and the ill-fated H24. I have also seen these on G22B, since PRR was also known for swapping similar tonnage trucks around.
To further complicate the G22 picture, they also had two versions of the 100-ton non-Crown trucks, as:
2F-F2 100-ton, six-spring "no name" S.C. (steel, cast) 5'8" WB 26 3/4" journal C-E (coil elliptic termed non-harmonic) truck of 10,500 lb weight, AND:
2F-F4 100-ton, six-spring "no name" S.C. 5'8" 26 3/4" C-E 10,000 lb weight truck
Those last two look similar, and there is also a Railworks version of that one, with the same problems.
