Bloody hell this must of been an 8 foot but I didn't think the 85W 8' went back that far?

this was found on the floor under that 8 foot twin atlantic i've shown on other photos, this must have been the original tube. Never seen a brass cap in this style before

can anyone date this tube from the dot code?

Tube will be from that period I've asked the expert lol

Shoot, its always the rare ones that don`t survive

yes, i remember this pair of tubes in the fitting with Clipluve, about 1991, then some moron shot at it with a shot gun !!!! derelict building you see

Incredibly rare, I am glad to see you at least save the end even if it is only 8 inch instead of 8 foot! The Enfield date code is practically useless for older lamps since it runs on a 5-year cycle. This was made in the 1st week of January 53, 58, 63, 68 etc. Being marked Double Life I would expect it to be one from the 60s, but its rare to see such a deep cap in use at that time. Perhaps they were only used on the 8' tubes.

This is such a shame the rest of the tube is not intact good save though Phil
