Melos power amps? Help me ID

Hi there,

I am looking for some help identifying what I think are some Melos power amps.

My father, a lifelong audiophile, passed away in 2012 and we are finally getting around to liquidating some of his electronics. Almost everything has a model number on it, but I can't find anything on these.

There may be something on the bottom of them, but they are MASSIVE and probably weigh 150lbs each so even tipping them over would be daunting.

I have found a few pictures of Melos power amps, but the only ones I see look like they are half this size. As the company is no more, there is just no info out there. I am assuming that these in particular are especially rare though.

Link to the pics below. Thanks in advance for any help!
