Bulb for 5c/793 Lamp Holder

Dear All,

Does anyone have the stores reference for the bulb used in the Type B lamp holder 5c/793? Is there a modern equivalent that will fit?

Any information would be most welcome.

Kind regards,

Tim

I just located both lamps in a 1947 copy of the 1086. Both described as small bayonet cap and obsolete.

Having had a look at the only WW2 IPB I have, for a Canadian made Lancaster, the lamp is given as 5L/116. Given that the Canadians had their own stores reference numbering system this information may not be that useful.

What is useful is that the drawing number is given as E&I dwg 12019.

This holder is part of the Coloured Resin Recognition lamps, type A.

There are 2 lamps for the unit, 4W 12V, 5L/2075 or 4W 24V, 5L/2076.

The type B had a 6W lamp fitted.
