Better photos would help but I do have an opinion from what I can see.

It does look Germanic and factory made. I don't know what you see that looks handmade but it is a pure factory Bass. The bass looks beat pretty good. Ripping up the edges like that with the damage beyond the varnish is not a good sign of care.

The back seems like it might be plywood and the purfling on the back looks painted while the top purfling looks inlaid. Like I said better pics or personal inspection would be best to be sure.

I Think it's a post wwII Bass from what I see as well.
