Before you find this thread all too boring and nod off, perhaps you could answer my unanswered PM and forum questions about the R5/3 and DB191A blades?

Oh, very sorry but I thought I had answered that one but sure enough it would appear I have not.

Sorry to say I don’t have the specs you are looking for.

Sorry about that.

Have I said sorry yet?

Yawn…time to wake up…there is a prop thread to but into.

Rotol R2/4F5/2 & R2/4F5/3 props used on the Spitfire VI along with the R3/4F5/2 & R3/4F5/3 props used on the Spitfires VII, VIII & XI (Wrong! see post 14) all used Dural blades.

Back to bed…

The dH9A recovered from Krakow has been in Hendon since 2003

True but I and I think Sadsack are talking about a different aircraft.

Don’t you just love new posters who come here saying that they know something we don’t know then refuse to tell you what it is because it may just dent their over inflated sense of moral and intellectual superiority. :rolleyes:

Or it could be they have been asked not to say and they are honouring that agreement.

Pop along in a day or two and have a look.

Aah…the resurrection of the trolley acc thread.

That’s a nice one they have there Varsity. Not many of those left.

Now I’ve been doing some digging and I think I now know what Graham’s trolley is. It’s an Mk.4, Section Ref. 4G/1717. These utilised the frame work of earlier trolleys but had a larger box structure on top. This meant that the box had to be raised above the level of the axils and it also meant that the cable could no longer be stowed round the side. I’ve added a photo of a war time example (with post war additions) to illustrate. Date wise, the earliest reference I’ve found for the Mk.4 is 1949 but I wouldn’t be surprised if they are around a couple of years before that before that.

DH Type 4/4 is a bracket type prop which shares a number of parts with the props used on the Blenheim (4/1, 4/3 & 4/7), Lysander III (4/5), Master II and Martinet (4/8). The problem you may have noticed is that they are all Mercury powered so unlike the Peregrine they’re left handed.

Blade DP54409

Hope that helps (not sure it does).

Have you thought about an apprenticeship? The RAF Museum and I think IWM run them.

Aaah…hadn’t thought about it being a restored blade. That would explain a lot. Someone has restored it a panted it incorrectly.

I’d go with the information on the adaptor ring.

RA 10046 JCS
The drawing number with a suffix telling you that it’s a Jablo blade with a Cristofin covering and a Simple brass sheath on the leading edge.

JPC1832 / C RS
HRA 57226 C
These two bits of info suggest two companies have been involved with this blade. JPC is the Jablo Propeller Company (also known as F.Hills & Sons at one point in their lives) and HRA is Horden-Richmond Ltd.

S17 (1)822
Not a clue!
