B-29 propeller blade?

[Júlio Campos]

Found this at an antique shop being sold as being from a B-29. Image attached.
Could figure out that's a Curtis 814-3c3-18 blade.
Serial # 154850
Trying to identify the exact aircraft that used it or if it's actually from a B-29, as it seems that B-26 and P47 also used this model.
Thank you.

B-29 had Ham Std props according to the USAAF manual 03-20-1 Propellers & Governors for Service Aircraft (45-05-15)

I will try and find what that blade fits

What's the gear-ratio for the B-29's engines?

The Silverplate B-29s had reversible Curtiss Electric props as part of that mod but one of those would be a very rare find - lol.

I found this for B-29 and B-29A (erection maintenance manual)
