Old Gates things into DIY

So.. I found a real old Gates housing listed for 100EUR. I figured ill just buy it because the pictures showed it had a dome attached (pictures were bad) and my initial thoughts were to buy the Gates-Nauticam adapter, or possibly design and print one myself.

So i went to pick everything up today, and the housing weights a ton, cant figure out what camera its for as it just says Gates. Old one surely as it has viewfinder for eyepiece. Could be just pre-digital even?

Anyway i would have been happy with the dome (ended up being 140mm acrylic SP44), but the seller then said that i can take the other lens also. Hold on, there was another lens?

So there was also a Gates SWP44, in great condition. And this got me thinking more, can it be adapted and used with 28-60 on Sony kinda like as WACP? Or is it just expensive piece of glass that has no use anymore?
