Looks to be a 1929 model. The arm is VERY heavy and the needle (cut from steel) needed to be changed after EVERY play or it would damage the record. But, when you listen to the great sound, it is truly amazing for something so old and crude to work so well. Not a fan of Nazi era German music but this is the only example of something that sounds good on all of YouTube. Notice the great dynamic range of the record. Take a look and listen. Yes, that arm is as heavy as it looks. That screw on the lower front of the arm loosens the steel needle, it drops out, you insert another, tighten her up and go.
