Can anyone recommend a book or photograph which clearly shows the inside of the Lancaster rear fuselage specifically showing the fit of the H2S equipment. All the pictures I have seen show just an empty space, be they of surviving aircraft or historic pictures in service. I do have a set of four original photographs, but they may show an early development installation rather than a production installation. The equipment is sitting on what look like half-inch plywood shelves, not strong enough to withstand violent manouevers without collapsing. There must have been barely room to get to the rear turret with equipment mounted on either side, as well as the Transmitter mounted on the floor above the scanner.
Many thanks,
Andy

The V-Bomber NBS is completely different. The Lincoln was fitted with H2S MkIV, all the units were different, although it was very similar at system level, esentially a repackaged version of the wartime H2S with various improvements. Pictures of the Lincoln installation would also be very interesting!

Is the Lincoln set up not similar?

I know it’s not Lancaster but there is a V Bomber NBS system which has H2S Mk 9 in the Netherlands:

Which Mark of H2S are you aiming for, and how much of it do you have? I don’t know much about H2X, although a pal of mine has the manual, but I’d be surprised if the scanner is compatible with H2S.
I’m putting a MkIIB system together, as I’ve found it easier to find the units. The current job is building some replica Power Units Type 280.
If you plan to fit H2S one day, then you have the same problem I’m trying to understand, just how was the equipment installed in the rear!

Apologies, I thought you meant just the mounting rung and ‘hump in the rear fuselage as opposed to a complete system.
NX has H2X as you say, we are working in completing a H2S set up so hoepfully one day she’ll be all H2S other than the scanner itself which will remain H2X

And which picture shows the H2S equipment in the rear fuselage? As opposed to the Indicator on the Naviigator’s table. I’m regarding ‘rear fuselage’ as being aft of the wing spar, where the bulk of the system was located, as can be seen in my photos.
By the way, I think the picture showing the Wireless Operator’s position is actually taken in a Manchester, I don’t think the Lancaster was ever fitted with a T1083/R1082 system.

I suspect the former because they came with a training document which must predate the official AP for H2S MkII.I’m looking for similar views in a production aircraft, but they seem very hard to find.

NX611 has the American H2X fitted, perhaps I should have been clearer that I’m specifically interested in the British H2S fitted in wartime RAF service.
Correct me if I’m wrong, but I assume that NX611 was fitted with H2X post-war for service in the French maritime role?
Whilst not addressing my particular question, can you tell me whether the H2X installation is complete? In the various videos and pictures I have seen inside NX611, I have only been aware of the scanner and the main Indicator Unit for the operator to sit at.
In the case of the British H2S, in addition to the Indicator and Switchbox mounted on the Navigator’s table, and the Fishpond Indicator (added at MkIIB) on the Wireless Operator’s table, in the rear fuselage are the Scanner, Power Unit, Voltage Control Panel, Transmitter, Receiver, Modulator, Waveform Generator, plus two Junction Boxes. The units at the two crew positions are just the tip of the iceberg! A long-term project of mine is to build up a complete system on the bench.

NX611 has it fitted. Email [email]enquiries@lincsaviation.co.uk[/email] and ask for some photos
By: AndyY - 6th January 2019 at 19:32
Sorry, but not one of those pictures shows the equipment fitted in the back of the Lancaster! Lots of pictures of the Indicator and the Switchbox mounted on the navigator’s table, and of individual units, but not what I’m looking for!
