I'll try and give gateway a shout tomorrow thanks.
it may be a Sutton but I doubt it was sold as a bench top. I've used bench top McKay's before and this one has too many vital parts below the join line that were designed to be there. the spool is up high but was originally meant to go in the bottom holder on the left side there with the thread coming out the top to the right leg, wrapping around an adjustable nub (which was lost and most likely why the spool is now mounted where it is) and then entered the top right side of the resrvoir (black box on the front, lid is currently on backwards), dipped into the wax/lube and then up through the bottom of the horn.
in every McKay model that I can remember using, the reservoir was attached to the horn itself.
one thing is for sure, this puppy is pretty old and most likely rare. thankfully the parts won't need to be replaces until they get worn out after 10-15 yrs
