    If you take into account the hub i reckon we're looking for an aircraft with a prop diameter of 3.70m-3.80m.

    Anyone got a idea what a propeller like this is worth, as it stands (not knowing what type it is) ?

    Liklely not, your reasoning is a bit flawed. These blades do not butt up against one another in the hub, they are spaced at 33 degrees and the diameter for this size prop would come very close to 3.4 meters, not larger as you conjecture. The measurement tip to tip in a "Y" formation will always be shorter than a combination of the two legs in a direct line. Make sense?

    If you use the length of the blade in question as the radius (1.78m) the diameter will be 3.56m, if you then add the diameter of the propeller hub where the prop butts against it let's say 20 or 30 cm you would have a prop diameter of 3.76m or 3.86 m, The Stuka has a prop diameter of 3.40m including the hub so a single Stuka prop blade would be less than 1.78 m.Name:  220px-CIRCLE_1.svg.png

    Thanks for the extra info. I can confirm that this blade is from a Junkers Ju-188 High Performance Medium Bomber.

    The number 941211.15 identifies it as coming specifically from the Ju-188 A1 type that was powered by the Jumo 213A engine(s).The other 'A' series models (A2, A3 and A4 had their own respective prop serial numbers being, in order, 941211.16, 941211.17 and 941211.18. After the initial 'A' production series of aircraft using the Jumo 213A engines, the more powerful BMW 801 G-2 engines were fitted under the designation Ju-188 E series.

    There were slightly different prop spec. types used on all the 188 series, but Gunny Hartmann is correct in stating the airscrew diameter as being in the 3.6-3.7m range, well done that man!

    Total Ju-188 production ran to just over 1230 aircraft, so this is a fairly rare prop blade, especially when you consider that it was only fitted to the initial A1 series bomber. Below is a couple of pics of the 188 A1 that used this type of prop blades.

    Regards, Ned.
