hi

on my pigliacampo accordion label may be the answers i was looking for re bass reeds etc could anyone clarify?

it has n456 37/80 -3/4-1 made in italy =

guessing 456th model made /37 key /3 reed treble side

unsure 4 - 1 meaning :?

never seen this type of marking on a p/a

I'd say your guess is correct, then:
80 = 80 bass; 4= 4 bass reeds for sure; then not quite so sure but 1= 1 voice (if so, no couplers bass side)?

correct no couplers bass side
mystery solved (for now) thanks

Actually I dont think 'voice' is technically correct, but you know what I mean - there is no switchability to alter the reed bank combinations on the bass side, so only one combination available.
