Apparently they were RAF roundel blue which was the blue circle post 1938. Colour chart number BS381 110. Its probably surplus paint that which left over from WW2. Same as Land Rover green was the colour from aircraft cockpits I believe
I had considered hot bluing the 84 but have decided to have a go at powder coating it myself once I get round to making the oven. trying to decide on which blue to do it in as i want to get as close as I can to the original roundel blue
Hi I really like the look of your work. What do you use to stop the jaws and the slide from rusting. I've got a record 84 and a record 50 I plan on restoring
