I talked to Joe Petosa (via email) and he sent this picture:

It's got the same layout of switches as mine and has this nice grille covering up where the buttons were.
This accordion is well worth putting a little work into as it has some fine reeds in it and sounds wonderful.
I love the Tremelo/Violin/Imitation musette sound this accordion has.
I will post some pics if I decide to go this route once its finished.
