the search continues: I have asked lots of companies so far with no replys I took a photo of a scott and using paint shop pro and the web got a comparison of RAL 4003 – 4010 the best match to my eyes is RAL 4006
with RAL 4008 comming up behind. trouble is that photos and VDU’s are not the best way to get a colour match.I cannot belive that such an important scott detail has not been recorded somewhere…. 😯

Ah! just a smigeon would be good but alas

Or go to your local DIY store and get a bundle of those color cards they use for on the spot paint mixing. Those are not RAL but you could use those to compare at the rally and then compare the outcome with a RAL card somewhere later.

I was very lucky in 1967 to buy a 1928 Replica that had been in store since 1941. I had every reason to believe that the barrel had not been refinished.
From odd places where the finish had been chipped off, it was seen that the barrel had been polished and the finish was a tinted transparent varnish which, as the underlying polish of the iron barrel glows through, gives a unique appearence. True, you can get somewhere near the overall impression by using a non opaque paint, but it is definitely not the same.
I discussed this with Tom Ward in 1968 and he confirmed that this was indeed the process the factory used and he sold me a couple of little tins of tinted clear varnish that he had made up to replicate the original.
To do a quality rebuild takes much time and usually costs more than rebuilding other makes, so the least one can do is to try and present the job properly.
I send blocks to be polished at

I can recommend them for all polishing and plating without reservation and they do all my work

After polishing,I carefully apply a degreaser then apply about 5 light coats of an aerosol transparent glass lacquer.
After this, about three coats of a clear lacquer to build up the surface.
As with all aerosols, it is quick, easy and relatively foolproof, unless you try to apply it too heavily, in which case it can run.

I buy this in cases of 10 aerosols
I do not know if they will sell / send individual cans
I thought I would be able to sell these on, but the Post Office will not accept aerosols for carriage
I can send by carrier, but then the carriage price is higher than the cost of the paint.
I need to order another batch as I have another 10 barrels to paint in the next few months. If anyone wants me to take any to Abbotsholme, just advise on roger@mossengineering.co.uk

I used a high tempetrature silver base coat then used the hmg magenta glass lacquer with a final finishing of the synthetic lacquer.I have done about 700 miles since i finished the restoration and it still looks excellent apart from a little burning of the finish near the exhaust outlet.
