Lamp & Check Meet - South Yorks

[shotlighter]

Ah I didn't realise Nystagmus had ended before the protector lamps became available. I think the type 6 was 1929? This example is a bit of a franken lamp. It has the upper part of an RS and a base that was an SL. But I spotted the glass immediately on the listing so purchased anyway. You can generally tell as the glass will have a yellowy tinge, especially in natural light. It is basically similar to Vaseline glass that was very popular from the mid-19thC, but not quite as colourful.
The glass is really quite rare though, but usually seen on protectors. Sadly this example is cracked but I purchased knowing this, due to the rarity,
It would be nice to find out an answer!

Thanks for that, I was wondering if it might be a "mash-up", as I couldn't see how you would read a gas cap, with the glass obscuring the flame like that. It must be deputys workman lamp!
Have you tried emailing Protector? I had cause to call there several times in the early 2000s & and the owner (David IIRC) was very knowledgeable about the firms history. He seemed to have quite a good archive of old company documents too.
Might be worth a try?

My glass is not in great condition although you would see the flame through it. Bear in mind I am floursescing with a 365nm torch so it renders the glass opaque. There are scratches inside the glass that doesn't help as well.

Yeah worth giving him a shout I guess! Someone suggested the glass company is still active, based in Scotland I believe. Might be worth contacting them, if I can find them!

Didn't realise you had it under UV - I should of guessed given the intensity of green!
I've had a look through my old mining books re coloured glass to improve readability of gas gap. The only thing I can find is a paragraph in Statham's 1951 "Coal Mining" page 376 para. 1. Apparently blue glass was tried but clear glass was found to "afford infallible indication" anyway.
(I seem to recall once seeing a lamp with blue glass).
