Default Help Identify Flottrop Propeller

I just acquired some old wooden props, one is a Flottrop. The only numbers stamped on it are: A1188 and DES 7547 G - 46
Can anyone give me some help as to what that prop was used on, age, or any other information?

The only 7547 models I see are "S" designation, presumably for Szekely, which you can find on this page.

The 46 is likely the pitch, but I don't know what the "G" is for, and maybe a whole different engine.

Thanks, I believe this is definitely a Flottorp (I need to figure out how to spell it too I see). The very old decals are still on it.

Looking at the numbers and such for that period, it would appear that it was made for some engine whose name started with a G.
Could that possibly be there for "Government"? Does anyone recall an engine whose name started with a G?

How about the "G" being a "C", which would make much more sense. I have another reference showing a Flottorp model 7547 C, which has the same hub dimensions as the others and was designed for a 63 HP engine. The hub is specified with slight measurement differences, so I presume they were all made for use with the Szekely engine.

It was produced under Type Certificate 408, which expired on September 3, 1948, meaning that it could not be used on certificated aircraft after that date.

Nope, no chance at all. The propeller is in excellent shape, and the stamped id is very clear, and it is definitely a G. I will post a photo of the stampings for everyone to see if they read it the same as I.
Thanks for helping to figure this out.
