This has been posted on another forum. It was dug up on an ex US airfield and was posted as a grease gun(!) looks similar to a P51 emergency hydraulic pump. I can’t find a picture of P47 one, if they had them at all. Surprising that a US aircraft would have a manually operated unit requiring exercise! Any ideas?

Interesting about the part numbers, I can only find 55 as a prefix for AT6 parts. It must have been a standard NAA component for a while. The pump is definately P51 as it came out of the same hole as a very complete Mustang, including data plate, wing/fuselage gun selector etc. It’s in several pictures in ‘production line to frontline’ in the Osprey series. Computer is playing up and now will not upload the photo.

I have never seen a photo of the later ground fixed pump in operation but I can tell you the part number 109-580243 (complete assbly) and its very well illustrated in the IPC. Not sure about the 55 prefix as a NAA part/type number tho.

Sorry Steve! I spent a long time looking at photos of Ds and thought I was losing the plot. Lots of part numbers: Pump assem. No. 55-58024-5, Body Assem. No. 55-58024-10 and Serial No.5526-2885. I wish everything was as well labelled.

Hello Mark, probably explains why I couldn’t find find a picture of one on a D! Earlier marks (certainly RAF Allison models) had a pump on the stbd side of the seat. I have one with ‘Hand Hyd Pump’ embossed on the knob on the end from AG634 which is what got me thinking in the first place. Perhaps it’s P47?
Its Steve actually 🙂 I should have said I was referring to the D model manual. Are there any part numbers on it?

The P-51 did not have an on-board ‘Emergency Hyraulic Pump’. It did however have a hand pump that mounted on a plate on the starboard side engine frame (ground use only). This item seems to differ from the pictures of that pump I have in the manual so not sure thats what it is.
