For my birthday last year, I bought myself this antique accordion.
I have no idea how to play it, and it's probably way out of tune anyway, but it does make noise! And doesn't it look cool??? And, no, I'm not sure it's absolutely period, but similar accordions were around in the Victorian era.

Anyone have any ideas on how to mod it out into an even cooler steampunk accessory????
I was thinking maybe replace the mother of pearl keys with typweriter letter keys?

But what else could I do?
