Question about the front bolster #2959DX first one made for F-12 was webbed or open like an F-20. This was on all F-12 till FS 11755 than changed to solid bolster#3519DAX
FS 59358 and up. Waukesha engine was in F-12 FS501-FS3034 At that time F-12 got IH engine OHV and finished the year at FS4880 in 1933. I see very few F-12 with the webbed bolster, Was there a program to change or up date front bolster to solid?
I see many claimed Waukesha F-12 with solid bolsters even though they should by serial #'s that have the webbed bolster. This is the one tell tail sign that seem to through me off when looking for original waukesha F-12's. Any input on what this does to the value of a waukesha F-12 or not? When were the bolster's changed? oldiron29
