Is this dolly Marshall related?

[GKguitar]

This came with the old Cab I recently purchased.
Does anyone know if it is made by Marshall?
The tolex looks just like old Marshall type. I've never seen a dolly like this before?
Has 2 screw in type threaded attachment on each side.
Fits perfectly under a Marshall cab.

Nah, that's somebody's homebrew project.

 

[BygoneTones]

Agree, most likely a home made effort.

I believe that is for an old 70's Ampeg SVT cabinet...
