Does anyone know the frame plate thickness used on the D&RGW ALCO built K-28s?

Bonus points for the frame thickness on the: Sumpter Valley #19 & 20, K-27's, C-18, C21, etc. List all you can.

The only frame thickness I know is the K-36 & K-37's , they are 4", but those are the "big boys".

Hi,

Class 43 4-4-0 3"
T12 3"
C16 3"
C18 3"
C25 3 3/4"
K27-K37 4"

My plans for the C17 and C19 are not clear but would guess 3". Same for the Class 56.

The C21 and the C25 are supposedly the same chassis.

Just measured the frame on Sumpter Valley Railway number 19, it's 3.5" thick.
