I was really excited to get my latest CL find completely disassembled and ready to clean when I noticed something on the B stamp...no offset.
It's not in the greatest shape, so refinishing might be in the works anyway but I'm starting to think the chassis was replaced at some point. Didn't all of the #7001 RC10T kits contain the "offset" A or B chassis? My understanding on this is limited, but this doesn't look like no offset to me

Here's a few photos:
