Guess that figures. Rola later became Plessey. Always thought they were an Australian company and that the Plessey deal in the 60s was a UK buyout. Rola even used to make their own winding wire here in Oz.

That's a serious piece of restoration you have there. I'm mightily impressed.

Thank you very much.  I'm hoping to restart the restoration of the set at the end of this month.  

The electronics have to be finished off properly.  First job to attend to is the damaged line output transformer.

Thanks, that explains a lot.

So Rola UK were gone by 1949. The Australian company were more successful and continued well into the late 70s. They made speakers, winding wire, TV components and even electronic road signs.

That design of ED speaker may have originated in the US because apart from the paint colour it's identical to a model made here in the '30s.

News Flash!  Work commenced today on the final stages of the cabinet restoration.

At the end of March just about everything had been done with the reconstruction of the cabinet, just a few details to attend to.

Today's work was concerned with the front control panel, making it fit properly. The beading between the screen panel and the control panel needed attention. Two strips of veneer have been layered on to correct the shape of the beading.

The plinth the cabinet stands on has been tidied up but I believe it will be better if a replacement is made. The correct wood has been found to do the job and it's an easy part to replicate.

Hi Frank,  for the final finish of the cabinet surfaces I have to decide to either apply french polish or perhaps better still have the lacquer sprayed on as to replicate how the cabinet was made in the first place.

Why not just scrap the top bit and turn it into a field sequential colour T5?

I wonder if it still exists?

Hi Peter, is this an early two colour system? Also ,did Baird pre-empt CBS by a good number of years.

Hi Till, I really don't know but if the colour photo is accurate then I suspect your two colour suggestion might be right. It's certainly an odd filter colour. Looking in ETF there are some photos from a November 1941 report that show a colour wheel receiver that I suspect is 3 colour. The camera filter drum has 6 filters. See also here.
