I got another number today, a Minter, V9306. Ads from 1955 show a Minter with a Simplex, which means that the Simplex was being made in 1955.
I strongly doubt the lower V---- would be 1955, it seams to early, but I will keep open minded until I have more numbers.

My internet is out after yetsurdays storm so my posts and responses to messages will be slow, sorry everyone frown


Thanks for reading!
