I purchased the American Autowire Classic Update kit for my 1950 3100 project.

I bought it from board vendor MCB earlier this year, paid $495. I cut open the plastic bags to read the instruction sheets but other than that it is brand new, never installed, all parts included.
Now I'm going in a different direction with the project. Will let this go for $395 shipped.
