Jan,
Generally sand domes were moved to get shorter pipe runs
that were less likely to clog up or to transfer weight forwards
or backwards to balance the distribution of weight on drivers.

Thanks, Rupert! Well, that gives me a certain "prior to" date for that
first picture, which is incorrect from what was actually listed on the back!
The 2nd one then may very well be right after the rebuild.
But that still begs the question as to WHY the sand dome was moved...surely
it wasn't for cosmetic reasons...
Cheers!
