request for info about a Hamilton Standard propeller

Hi members,

I will introduce myself first, Paul, from Holland. Just bought a propellor, just for fun.
Its a Hamilton. No idea what plane its comes from.
It has been in a restaurant next to an airport. That closed down and sold items.

Who can help me tell me more about this prop ?

It has some code / numbers:
- DWG 6477 A
- 1 CHG D H.S.P.5
- MFG .NO. RR. J. 3510
- CONT - W535-AC-29749

I would love to hear more about it, as where I can find info myself on the internet (eg. where I can find out more about the codes / history etc....)

hope to hear from you guys

Regards,
Paul

From memory the 6477 blade was fitted to the Harvard/AT-6

I think the kind of prop blade was also used for B-17F/G, B-25, Ventura, C-47,

Looks like you're right - the AT-6 had the 6101 blade..

could this propellor been used on a plane during the WW2 ?

I'm not sure. Judging by these red strips at the tip of the prop blade I would say that's the post-war one.

What is have is a single blade from a propeller, not the entire propeller.
The Manufacturer's basic model is 6477, "DWG 6477 A" is the drawing and parts assembled on to the blade; the letter can change for different items like de-ice, and cuffs, but this blade is just the basic.
The "-1" is part of the blade model, which means the reduction in diameter of the entire propeller assembly.
The "CHG D" is the engineering drawing change that that the blade was manufactured to.
The "H.S.P 5" is the alloy that was used to manufacturer the blade from, this is considered the "soft" alloy blade.
The "MFG. No. RR. J. 3510" is the manufacturers serial number for the blade; the "RR" is the actual contract manufacturing facility, which is Remington Rand.
The "Cont..." is the war time contract that the blade was produced under.

As previously mentioned it was the standard paddle blade used on the B-17, C-47, B-24 during WW2, in basic propeller model 23E50. Post war service was probably on a DC-3/C47 or variant. No way to trace the history, but you do have the contract number, so there may be able to trace dates from that.

Wow.... Thanks Michael Hope !!

That is exactly what I was looking for. Great info.
Now find out the contract...

In 2 weeks I will pick up the blade (not propeller !) and will try to find out more from previous owners, if they are still around.


I used to own a Willy's Jeep, 1943. This Jeep was also produced after the war, but once an item / car was used during war, its always more collectible..
How about propellors / blades ?

Will keep you guys updated.

Picked up the blade . Have new photos.
I also sent a message to Ratier Figeac, as the sticker on the blades shows "Hamilton Standard, repare par Ratier Figeac"
Hope to get an answer from them soon.
