I've been learning accordion slowly during lockdown.
I played for about 3 months around 40 years back during summer holidays from univerity, then the accordion was 'lost' somewhere in my parents house.
Then I found this on Ebay a couple of years back and overhauled it fully:
1959 Hohner Lucia IV P (LMMH 96 bass)
Roll forwards a couple of years and I've now got 4 accordions.
Quite handy for wet weather.
