Blister window ident

Hi FarlamAirframes,

Looks like the late production Beaufort Mk I had the same (or very similar) antenna housing.

From Blenheim book (detailed guide by Norman Franks) 

• The clear loop housing shown is a full ADF US football style antenna housing on the upper surface/dorsal spine.
• The Blenheim  cockpit side window was a blister- but a full cast item. The Bisley nav window was also sometimes blistered but again cast that way. 
• The clear FN54 turret was a three  piece.
• There was a blister shaped azimuth receiver in the wing fillet  – aluminium and not correct shape.

But looking closely at the ADF football antenna – it is in two parts that are bolted together. 

The part I have has a disturbed side – the casting is shaped around a curved disturbance on one side. I had assumed it was a bad casting. Is this where it went around a mount?

Is this the starboard side of a two part clear ADF antenna similar to what is shown in the attached picture ?

P.S. an earlier discussion on aircraft DF loops

Thanks – will check  that lead out!

Blenheim Mk V (Bisley)? Some of them had a clear loop antenna housing. I think I’ve seen a pic of the Mk IV with the same but can’t find it at the mo.

Spitfire canopy 19.75 inches front to back. Blister 22 inches long.

Sorry.

It also looks like this ADF antenna housing

Thanks Tony I will check size vs window length

for more images

It almost looks like a Spitfire one…

Sccroll down the link to the PR Spitfire image and you will see the blisters they added to the canopies

Chris thanks but  it is not that large.

It is very similar to the aluminium antenna loop covers that are for sale in US. But made from perspex.

Could it be from under the rear fuselage of a Halifax?

Thanks FA, can’ t say it’s improved my memory but at least it shows it’s a housing rather than an observation blister.

With the need to drill a hole at the lowest point, I assume it was to be placed on the underside of the airframe.

Bit big for a lamp, would still go with aerial of some kind?

AM – as requested..

It looks half familiar, in that I’m sure similar ones used to crop up at the early ‘ jumbles.

I want to say American and nav aid “radome”.

Can we see the label, it might jog my memory a bit more?

Cees thanks for the thought but the labels are still original and  waxed in place so it looks like New Old Stock.

The outside edge does look bandsawed but I assume that is how it was finished by manufacturer as it was made..

Could it be that it was cut out and the rims trimmed for display?
