Default Aleph 60 prototypes?

I recently got the opportunity to pickup a pair of what appears to be Aleph 60 monoblocks. The front faceplates show nothing but are identical to anything I can find. The rear does have stencil with pass labs info. No serial numbers however. Upon opening them all PCB look to be good but there seems to be a bit more wiring (point to point) resistors in parts of the board.

Anyone have any idea of these are original somehow prototypes of some sort?

Here's the rear. The PCB I'll upload a picture of the point to point soldering it has.

Here is the PCB and notice the solder modifications. Also no faceplate silkscreen. Were they ever released that way?

Better views of PCB. They sound great but I don't want to pay too much of they are DIY clones. Which why I ask if maybe some kind of early prototypes. Any help or advice would be helpful and appreciated.

They appear to be prototypes. Usually these are made in small batches and were
not intended to leave the factory, although sometimes they do.
