You're most welcome, Mike! 
Just to make sure that I don't inadvertently lead you astray, the propeller I mentioned as an example is, I would assume from the "LH" part later in the string, probably left hand rotating, and there is also a prop (otherwise identical) that is right hand rotating. The front page of the Prop Shop website says that rotation is based on the UK/Us standard, which apparently is opposite the German one … I don't remember off the top of my head what this means, but one thing it obviously does mean is that one needs to make sure one gets the appropriate kind for whatever one happens to be building.
