Yes, a client of mine used to have a big 40 (odd) channel ACES desk. They were also branded SECA (ACES backwards), which is what this one was.
It was quite well speced, but from memory the construction quality was probably like an early Studiomaster. Anyway the friend got rid of it basically because it was worn out, & the faders/pots needed replacing amongst other things.
I think that with this company they offered you the likes of a 2" 24 track and big mixers at the absolute cheapest you could buy them for, but ultimately you get what you pay for !!!
