[speeders] OD A v/s OD B

[Snetsinger <mike.mitzi@sympatico.ca>]

Group,

I lucked out and and found an OD A (1941) that is in fine shape and has
good compression.  850 km round trip to get it.  It'll replace a
thoroughly messed up OD B (1942) for our M9.  I was wondering if there
is any difference between an A and a B  model.  Any thoughts?  They sure
look the same.

Thanks,
Mike Snetsinger
