I have been looking for a picture or drawing of the base mount for a Mk I Nav light. These were the type that are bullet shaped and sit atop a long arm above the wing. It has taken ten years to find one light for sale. and it was without a base.
The RAF museum has some nice photos of said light, but all are missing the base. It would actually be enough information just to know if they are three or four bolt bases. Any help would be appreciated.
Cheers,
Ed

The two following items are needed: #14186 and 14189. They are parts of the fuel tank where the fuel quantity indicator attaches, and the valve fitting where the fuel leaves the tank.
Thanks!!!!!!

[ATTACH=CONFIG]235619[/ATTACH]Hopefully this will show the Mk II nav lamps that I have been talking about. Major credit would go to Alan Hulme who has written an article or book with this information. I wish I could add more, but do not know this info. Please enlighten the rest of us if you have such info.

Hi Ed
I hope to be going to look through some more Bristol drawings in the next few weeks. Can you let me know if there are any specific drawing numbers you are looking for regarding the Bulldog ?.

No sooner did I post my last, than I noticed that it should read 5C, not 6C. Anyway, I believe you are correct with the “Bracket” that has no individual part number. So it goes…on and on….
I did try to contact your friend (twice) but still no answer. The thought of vacuum forming has been formulating, one for cost, and mostly for weight. The lamp on the rudder is a flutter inducer, as well as ‘souvenir’.
Thanks for the info, and I shall keep trying.
Cheers,

It mentions mountings in section 5C but not sure if it’s the same part going by the description.

BTW Ed, did you contact my mate about making up the missing lamps for you?

Any idea what the base socket or plug might be listed under? 6/??? I have been searching the web for RAF ele. parts, but nothing yet.

Thanks for the help. I have seen the picture of the lamp base above, but find it hard to believe they would make it that way. I would envision a base with three screws with a vertical lug for the standoff arm to attach too. But I can see why your statement of vanishing bases would be true.
I may have one of the reports, will check when I get home (busy slurping G&T on Molokai) Will also try to upload some photos to this site. The ailerons are built, need one last coat of varnish and lead weights.

Ed1,
Here is the nav light, the base explains why most of the stolen lights don’t have the base !

Here are some flare holder dimensions for good measure :

I have recently unearthed
Farnborough Report BA 1621
“Notes on the effect of Nose shape on the characteristics of Frise ailerons 1940
and
Farnborough Report BA 1624
“An analysis of aileron performance 1940” – mainly Hurricane
That’s worth a little photo of some of your magnificent Bulldog work !!
