Nice one, how old is it?

Code is 4c followed by a circle with a dot - the etch is dot matrix orangy yellow colour

Ah, March 2014 before the last ones with the etches on the caps

Glad your happy with it

@Beta 5: Thanks really is now a while ago, March 2014 - was still doing my A levels and attending the youth orchestra which still feels like yesterday and not 11 years ago!! @Danny: Thanks yes I am happy with any SOX lamp in my collection, I realise I need to build up the collection as currently I have 2 only

If it’s one of Danny’s it will be a good one , I don’t how he picks them, but even the used ones that came from Durham are almost like new!
