I think that storage and weight limitations were a contributing factor. Early turrets did not have feed systems to pull ammunition from locations outside the turret.
They were limited to what they could stow in the turret.
Hi Elliott,
Far from complete, but this is what I have so far.

Hi Graham,
I have attached a two images taken this past winter of the turret belonging to the CWH Boly project. The other is from a diagram.
The actuator in the first image appears a bit to long to be from the turret, but it could very well be. There seems to be two or three times the number bolts in the flange section of the actuator.
The Bristol centre turret has a three actuators – elevation, turret rotation and gun rotation. I believe that the elevation is the longest.
In the second image, the part second from the left appears to be a part of the valve box near the gunners feet.
Regards,
Mike



Looks great Cees!
What type of finish did you use?
Cheers,
Hi Elliott,
Sorry for the delay.
I hope you’re not in a huge rush. I’m drawing up a rotation lock and plan to start drawing the valve soon.
I’m still in need of an elevation ram. Any information you might have to share would be great! I’m also interested in the possibility of having a second wind baffle made.
Might you have any pictures of your project to post?
Cheers,
Mike
Hi Elliott,
Those parts look familiar!
I don’t have any spare filters, but I could possibly do a cad drawing of the Palmer firing control valve as I have one sitting on the bench at the moment.
Cheers,
Does anyone have for sale a spare turret seat for a (Boly/Blenheim) Bristol centre turret?
Please send me a PM.


I have no plans to dismantle it.
It’s another piece that my dad picked up at a local farm. My understanding was that the rotting fuselage was picked over for it’s fittings and this piece was left behind in a pile.
Unfortunately, the identity will probably remain a mystery.
Very nice find!
Is it more valuable for the fittings, it’s use as a pattern/template or as a collectible?
Unfortunately that’s all I have.
A great book on gunsight theory is British Aircraft Armament Vol.2 by Wallace Clarke, R.













Some photos from my visit to the museum shop last week.















Yes, they attached to the rear sear release.
The rubber line has deteriorated and I was hoping that I could replace the hose and the brass crimped section.
