trade operators manual

[gus]

I have a very nice 40C operators manual. I'd like to trade it for a 420C operators manual in like condition.

Attached photo. Some dirt and a scuff or two on the cover, probably from being in a drawer. The inside is close to perfect.

I saw another 40C OM and the cover was not the same?? Since I couldn't read it well, it might have been from another year??

In any case, this Operator's Manual is numbered OM-T9-555.

Did they change manuals each year? I cannot find any dates in this one.
