http://www.airfields.fotopic.net/p47364080.htmlYou might want to ask the question on AiX too, there will be guys there who would tell you how it all worked!
Richard, thanks for the link to the photo and I will also have to check out the AiX forum.

This is not the same as the machinery we have at the museum.
The pieces at Nanton seem to be for something much larger.
Mystery solved…..I found this online today.

Nice pair of jugs!
I saw Hun Hunter & Wicked Wabbit along with Tarheel Hal & Jacky’s Revenge last summer at Thunder over Michigan.

Oooo, are you offering it?
Just curious to see if others have a factory cutaway of something related to historic aviation. Perhaps they could post a photo or description of it.
Thanks for the tips!
I’ll see if I can source some mould protection spray locally and give it a try.
Any recommendations on how to preserve bare metal gears that operate without lubrication?
All parts have been dismantled and blasted.

I took a few pictures tonight of the two armoured screens in our collection. I’m still not sure what type of aircraft or even vehicle they might have been fitted to. The panel (at one time) swivels and there appears to have been held in it’s up/down position with a locking pin and metal stop tabs.
The outer steel frame of the glass measures approximately 13 3/4″ wide by 14 3/8″ high, not including the tube at it’s base.

Hi John,
I’m curious to hear your theory/method of using the bungees to retain the gun release pins. My dad found our only gun release pin on the floor of a turret.
I certainly enjoy sharing details & photos on this subject. That is what makes forums like this great!
Regards,
Hi Walter,
I know all about house renovations & turret projects! Any chance you might share some photos of your turret model?
Correct, the photograph is also of a FN121 turret.
I’m not sure what the photo flash bulb is for. If you do find out, please share with us.
Regards,
Hi John – There are no clips or rings on these hoses either. The loose ends of lines where simply placed into the bungee loop.
Hi Walter – Thanks for offer of help with any FN4A details & photos. I have tons of turret photos too, if you ever need help yourself…..give me a shout!
Are you working on the same project as John?
Here is what I could dig up…….
AP2799F, Vol.1 – FN121 Turret

I hope this helps.

Mike
Hi Walter,
It supports the flexible lines to the sear release when they are not attached to the weapon. Probably so that they don’t leak.
I will try and find you a picture.
Regards,
Are you sure they`re aircraft ? they look like the armoured screens fitted to ww2 special forces jeeps.
I have always assumed that they were from an aircraft. There is also a knob at the base for some type of heat/defrost system.
Nice shots Andrew…
The museum looks a bit more roomy now!
Hi Alex,
Very nice work!
More on sear release types can be found here:

The BP Type E turret uses a side mounted electric solenoid sear release at the rear of the weapon. It looks like a soup can and might be the same type might be used in this turret.
The casings and links are ejected through the bottom of the breach.
Happy Holidays,
