Thanks Terry.

Yep, 13 is for DH.113 and 15 for 115. This is generally the case for Flamingo (95) onwards. However, the use of the letters changed radically from some point around the time of the Venom (112). Many parts for DH.100 were used on 112, 113 and 114, many from 113 on 115. They did actually start to float backwards as modifications. The ejection seat mod on the Australian single-seater came from the Venom FB.4.

The exact cable path and how it is secured I am unsure of, but hopefully the following will explain the general idea. The cable only relates to the two shoulder straps; the lap straps are unrelated. For the seat that is lower down – the Navigators – the shoulder straps continue upwards to the cross-tube so they are stable and aren’t at risk of flopping down either side of the seat. On the other hand, because of the height at which the pilot’s shoulders are and because the cable goes to the cross-tube at such a height that if the straps weren’t tied together and guided, either the straps would slip down off the pilot’s shoulders or if the cable wasn’t guided, it would tend to go to the left or right. I’m not sure if the channel has a roller or a pin, but the cable doesn’t go all the way down the channel; the channel extends down the back of the seat so that the channel has continual stiffness to stand up from the top of the seat.

Looking at your photos again, the assembly p/n may be 13F45_A; so that dwg would include a definition for 13F377ND.

Good to see some Vampire questions/interest – these things are so sparse these days! I saw these seats on eBay back in November and was curious about details. I have a pair of Vampire RAAF T.33 or RAN T.34 seats. The first batch of Australian RAAF trainers were redesignated T.35A when given ejection seats and for the RAN they became T.34As. I will have a look at my notes on my seats tonight. I can’t find any photos.

I’m not sure if all the photos of T.33s or T.34s that I have are digitised, but this is the only one – below – I could find at this point which gives any suggestion about the head bump pad. The aircraft is an RAN example. Terrible as it may seem, I don’t think anyway that they did have them. There are at least two T.11s in NZ still in the fixed-seat arrangement – one with the RNZAF Museum and one restored about 20 years ago privately. In the UK, Alan Allen has one of these that, IIRC, he sourced in South Africa. I haven’t heard from Alan for a few years now.

My areas of interest are single seaters and the DH.108 so I would gladly swap my trainer seats for single-seater seats!
