Hamilton Standard Propeller blade from PIMA , ID

[merklesmisfits]

Dear all,
I am based in the UK , and have been an aviation historian, Archelologist, researcher for ever since I can remember.
I recently swapped a part with PIMA USA , and in return they sent me a big box of assorted WW2 parts .
I have. Propeller which looks very clean apart from someone trying to scrape off the paint.
They thought it had come off a mustang, but I want to double check, as one pilot said mustangs don't have de-icing boots,
My argument was , they might not need them now as they are not flying at 30000 ft in all weathers, referencing the air show or private owners circuit / operators of Mustang types .but perhaps they did whilst in service ? , truth is I do not know, and I cannot be sure it is P51
Definitely a paddle prop, Dwg No/ 7007F-7 as far as I can see ?
Can anyone advise ?

IMHO not the P-51 Mustang prop blade but a post war prop one DWG No. 7007A-7 or 7007B-7 used in 50' and 60' for the Grumman Albatross HU-16 flying boat for instance. The 43D50-611, 43D50-615 or 43D50-639 propeller. The DWG No. 7007F-7 should have the wire element heater.

Yes she certainly has a wired icing boot , the wire was on the opposite side, cut short , would this particular prop been used on any other type of aircraft ?. And Thankyou so much for your very helpful response

It could still be off of a Mustang as I think it is pretty common practice to use Albatross blades on Mustang restorations.

No, the list of the governors and propellers for service aircraft ( T.O. 3-1-1) released in 1963,1964 and 1967 mentions the HU-16A,B aircraft and the engine R1820-76B only.
What are the dimensions of the blade? 63 inches tall and 11 inches wide? There should be more markings stamped on the blade bott. Eg. SHANK and HSP. The HSP should be 26.

The excerpt from the list ..

Hi, when I am off work, I will remove the bottom and se if any more stamps are on this prop

You can still purchase new license build Mustang Blades.
The 7007 blade is Nickel plated, so a lot of work to remove the nickel plating to adjust the diameter to match a P51 blade.
They were using these blades on the DHC-3 Otter as an option.

Here is a quote from the Aircorps Aviation page on the restoration of the CAF P-51C.

September CAF Red Tail Update | AirCorps Aviation

by Chuck Cravens Lining up the wing and fuselage, almost ready to join. Update Some very significant events have happened this last month. Many assume our restoration shop is at the airport but that isn’t the case. It is 8 miles away in an industrial park. So, along with the usual restoration...

Another job was removing the nickel plating on the prop blades. The supply of P-51 propeller blades is becoming smaller and smaller, so they are difficult to acquire and very expensive. There is an STC ( Supplemental Type Certificate) that allows the use of Grumman Albatross blades on P-51s. Due to the expense and limited availability of P-51 blades, the Red Tail takes advantage of that STC and uses these blades.

All sounds good with the adopted Albatross prop blades for the P-51 but the one still has the nickel plating. What is more it still has the electric heating system for the prop that the P-51 didn't use. All that indicates a prop blade not used with any restored P-51.
