Somewhere in the back of my mind I think the "A" signifies Anderson, SC. But, were some FWs manufactured in Anderson? Someone will know.
I found this quote on ISMACS concerning the manufacturing of the 301a; "I no longer own this machine, but I thought it would be nice to include. This machine is identical to my 301a in body style and parts. The "a" in "301a"stands for where the machine was made - Anderson, SC - and is the only difference between them."
