I.D. help with a recent purchase

[Nathaniel Meyer]

Hi-
I just picked up this bass at a yardsale and was hoping that you good folks might be able to tell me a little more about it. Inside the body it has a sticker that says "bass copy of Antonius stradiuarius cremonensis faciebat anno 1721 made in germany bkn" I've seen similar postings on this site, but nothing real exact to what I've got. The guy I bought it from said he had a picture of his uncle playing a local hotel in 1950...
The metal bridge is not original (you can see the footprint of the old traditional kind) I'm pretty sure its a framus bridge. I included pics of the main issues- a crack in the heel and the endpin is pulling over...
Whaddya think? I'm hoping to get this playable, as it would be a great improvement from my chinese junkybass.
