Hamilton Standard Propeller

Reddington · Jul 3, 2025

Team,
A friend of mine in Belgium just recently found a Hamilton Standard propeller and was wondering what it may have come from. It is 116.5cm long and 21cm wide. Attached are some pictures. Any help you can provide will be greatly appreciated!
It also has these markings on the bottom:
Dwg 6100IA 12 Mfg 14387 CPL CONT - W535 - AC - 27731 - SUPP - I

Are you sure the DWG number is 6100IAbut not the Dwg 6101A? There should be one or two more digits after the "A". It may be 6 or 12. Judging by the date you posted it is DWG 6101A-12 isn't it?

If I'm correct the prop blade was used with many planes powered by the R- 1340/R-975/R-985 engine series with the 9 ft. 0 in. or 9 ft. 1 in. diameter two-blade props.
The planes list ....

AT-6A,B and C, AT-13, AT-15, AT-16, AT-16A, AT-21, BC-1, BC-1A, BT-9B,C and D, BT-10, BT-12, BT-13A, BT-15, UC-40,A, B and D, C-64, UC-64A

IMHO, the most probably aircraft for the prop blade seems to be the North American T-6 Texan , here in the Europe also known as the Harvard.

The blade by the length you gave and the shape of the blade tip, it like it is a "-24", i.e. a 8 foot diameter. so at that diameter it could not currently be used on an AT-6, it may have been cut down in length due to damage.
Are you able to get more images of the numbers on the blade shank? Also are you able to get a part number on the bracket as that would help top identify the possible propeller model that it was used on, the number could be "50390". Below is the different brackets that could be used.

Thank you both for the help! Here are all photos I have of the serial. I appreciate your help!

With no doubt it is the DWG 6101A-12. It is listed on the List of Propellers and Governors for Service Aircraft documents from 1945 to 1967. Although it's mentioned in 1945 with all the planes I posted above in 1963, 1967 the one is listed for the NA T-6G only.
However I agree with Michael Hope the prop blade should be longer but it may have been shortened due to the damage. And for the reason it couldn't have been used any longer and was decommissioned.

Hi,
If that blade is well short of the correct length and unusable due to damage, it may well have been cleaned-up at the tip just to make it pretty as a relic. I notice that the H-S Decal is very weathered but retained whereas, the paint at the tip looks unweathered.
Worth noting that some privately operated props get seriously reworked by poor owners!
