Guess they'll be running a precooler in reverse to create an adequate preheater for the test airflow ;)

Schneiderman: hand-loaded? Ouch! One shot per pass doesn't seem to go with the number of rounds carried, and having looked at video of 6 pdr firings the recoiled position doesn't seem consistent with the pilot position (and would require a mechanism to latch it in the recoiled position).

Chris: escape hatch I would presume. Several other WWII era pusher concepts used that as a mechanism to ensure the pilot cleared the propeller disc.

Not smart for an aircraft designed to fly at low level

I have not been able to track down the original (source) bay auction page.
Good starting point https://www.secretprojects.co.uk/forum/index.php/topic,413.msg310605.html#msg310605

On the patent drawing, what is the arc whose radius is labeled '27'?

Regret.

V.1000 was cancelled 29/11/55, prototype 80% complete, cancellation charges to us: 4Mn. 6 were on order as RAF transports for elite tasks (Hastings about to be replaced by 20 Britannia); an RCM variant (=ELINT) was anticipated. They were all replaced by 10 Comet C.2/T.2 and 3 R.2, which were capital-free, BOAC-rejected. No grounds for complaint there, GRE. So....VC7 pitched to BOAC, who declined.

So were DH schemes (Comet 5, D.H.118), which were funded to 2/57 by an MoS Study Contract, 10Mn., like GRE had enjoyed a V.1000 R&D contract. It was open to V-A to buy access to MoS' Intellectual (and physical) Property in the cancelled V.1000 - say a Reversal of the normal Launch Aid Sales Levy. If this was a blunder, a missed market, then GRE should go to Vickers Ltd for PV funds...
and exactly then he did, for Vanguard. That, he perceived, had real sales potential. Just like DC-8 and 707 did.

James Martin was notorious for redesigning mechanisms, including gun mounts annd feeds, usually with some success. No doubt he had some compact loader in mind for this aircraft but I have looked through his other patents but cannot find anything of that type.

EDIT....actually I just read through the patent and surprising Martin says this.....

Thanks, that doesn't appear entirely consistent with the Molins which has a feedtray to the side of the breech, whereas the patent illustration seems more like it surrounds the breech. ISTR some of the 40mm S Type feeds may have been similar. Possibly Martin intended scaling up an S Type feed, though it would be entirely consistent of him to get distracted into designing a new feed of his own.

Anyone know what that hexagonal block immediately aft of the main VLS is? It's obviously a launcher of some description, with two inclined tubes firing to either beam, but the description doesn't identify anything it might represent. Kalibr and the SAMs will be in VLS tubes, while the 2x4 Paket-NK launchers are probably behind the dark panels on the hull aft.
