I am currently advertising my Aeola (Model 17, 48 keys, Reg. No. 34801, 1937) on the buy & sell forum and someone has asked me what type of action it has, hook type of rivet type.
I have absolutely no idea, so I took one of the ends off but could not work out how to get at the mechanism. At that point, I got nervous and put it back together again!
Can someone help with this question please?
