I did think the first photo may of been first time in dry dock April 1911. But those added on wear plates and partly covering up the feet numbers on the rudder post came at a later date. They certainly look very clean and never seen sea water at that stage.
Good sample were health and safety didn't mean much in those days, as that man hanging on to the propeller with no safety harness!
Matter of interested were did you find the photos?

Here's some interesting changes made to the Olympic Class wing propellers:

Hey folks,

I have been going over the information about the various pitches and ogival configurations on the propellers of the Olympic-class. You guys are awesome.

The picture of Olympic having her screws worked on (Charley’s first pic) raises a couple of interesting questions, however.

How would the ‘cylindrical’ hub affect the ships’ performance as opposed to the ‘rounded’ one? A different range of pitches, perhaps? Less weight for the crankshaft to turn? The cone covers fitted to each appear to be identical, regardless of which one was used.

Would different propeller hub configurations on opposite sides of the ship create problems (balance, vibration, etc.)? It seems it didn’t take much to throw off the smooth operation/turning of the screws, and make your ship “happy-tailed”.

Thanks!
