I think they were re-badged Antonio Merloni machines i.e. Servis.
There were a few 'distributor brands' in Ireland, particularly during the 1970s and 80s which sold re-badged machines. They were just owned by the appliance wholesale companies who had a big enough market to be able to order own brand machines.
Main ones were:
Thor - (Rebadged Colston and later Ariston machines) no idea where they went! They had a very high profile range of washer dryers in the late 1970s / early 80s e.g. the Thor 850XD which was a Coleston/Ariston elsewhere. Our particular 850XD had a second label on the back saying "Riber Italia" (Never heard of them, but perhaps they were absorbed into Ariston)
I've recently seen the Thor name on really bottom of the line dishwashers, washers and dryers sold in a DIY chain here. They looked cheap and nasty.
Domotec -
They re-badged machines from various manufacturers under the names "Novum" and "Domotec". They now seem to target really cheap landlords. I haven't seen any of their products outside low quality budget rental acomodation.
They distribute some BOL indesit and fagor stuff too.
Powerpoint:
Again, a re-badging operation. It sources from the likes of Antonio Merloni, but also others. Again, they're budget appliances often with very basic features and plain design.
In the 1980s, there were others like Snowcap etc. ESB (The Electricity Supply Board) had a retail arm in those days and it also engaged in generic rebadging. However, in general their appliances were quite mid to high end. They had their own 1980s Hotpoint machines, I can't remember under what name though. It was more like the way John Louis in the UK sells its own electrolux machines.
From what I gather Washmeister was also a re-badging operation. They were usually Siemens / BSH machines and date mostly from the 1970s/80s. Some of them may have been baucknecht too.
In more recent years, those kinds of re-badging companies have all but vanished.
