B2 Ashtray light

[Addicted]

When reassembling my centre console last night I realised I have a lamp 'spare'... ones illuminates the heater controls, the other illuminates the cigar lighter.. but the third?

As we all probably know the final bit to be fitted to a centre console is the ashtray, this is when I realised that this spare lamp is intended to shed a dull red glow into the ashtray.. however the lamp holder is clearly missing. I'm assuming theres some sort of mounting that attaches to the ashtray, I can see a suitable pair of slots

Does anyone have one? even if not to sell a photo of one would be helpful..

I don't smoke, I just like the idea of having the right bits in place!
