Correct me if I'm wrong, but the "R92" would imply that the drawing for 
the 354912R92 panel has gone through 92 revisions without the part number 
being changed (the first version of the part would have been 354912R1). 
That's how a lot of the government drawings that we deal with are 
numbered, especially the older ones from back in the M48 and M60 days. The 
basic drawing number in this case would be 354912. You add the revision 
number to the end of the part so you have the flexibility of ordering 
older style parts when you don't need all the revisions/improvements 
incorporated, or if for some reason you can't use the latest part. 
Sometimes after several revisions/improvements parts don't remain totally 
retrofitable into old equipment. It's one of the bigger problems we have 
here with making things better for the army without affecting 
interchangeability between vehicle platforms. When the improvements become 
too drastic, we assign a new part number and start the revision process 
all over with the new part.

If this is correct the 351508R2 had a very short life, since it apparently 
only went through one revision before being replaced. Probably not very 
many went into production. In fact I would guess that just after it went 
into production, somebody realized a major concern/issue with the panel as 
it was, and a total redesign was started right away. Cubs that had already 
shipped were probably retrofitted at the dealer or were just left alone. 
Doubt if there was a recall effort to make sure all the shipped Cubs had 
an improved 354912 series panel.
