I Need Help Identifying this unmarked 3/4. (Pics included)

I picked up this carved bassed (maybe hybrid) for a pretty good price, but through all of the searching, I have yet to find a matching instrument.

The scroll plate looks just like an EH Roth or mid 20th century Juzek/Wilfer, but I have not been able to find a match of this neck joint.



More pictures to come later, I'm mobile.


Edit:
Enough mobile excuse, I'm back at home and posting URLs!

Here's the color of the original finish:
I lowered the string length from 41" and I believe this is a hybrid bass too.


If you'd have any idea what it might be, please drop me a reply. All I can think is Wilfer/Juzek or some type of German factory gamba.

Upper bout: 19 1/8"
Lower Bout: 26"
Depth (rib depth?): 8 1/4"

Thanks for looking!
