Help identifying accordion inherited recently

[SavoryApple]

Hi all, I didn't even know my uncle owned an accordion but it suddenly showed up and is said to be 70+ years old. It's in terrible condition, but I'm curious if anyone knows anything about this brand? I can't find any information online (attached). Its got a palm switch as well as one above the bass buttons and is 41/120

Slasterfonic?
Jlasterfonic?

Perhaps "Masterfonic?
A more encompassing photo could help?

very interesting!
Perhaps part of the logo on mine is missing a piece, because this "Masterfonic" accordion has an eerily similar one:

Masterphonic was possibly a Jobber brand, as the accordions
themselves were such a wide variety of models and styles
that a single source is unlikely. also, they are seen in various cities
of the USA, so it could not have been a private label of only one
teaching studio. apparently the name existed from the early 1950's
through the end of the 1960's at least

i have never seen any models above what would be considered
Student line accordions, except the occasional one-off for the
teachers themselves to use at the schools and events

they usually played and sounded pretty decent.. and were
usually rugged and solidly built
