Two is one, one is none, that's my motto.
My point was to illustrate... And therein lies a fundamental difference between us, Kurt. I didn't post to prove a point, I posted to help a fellow modeler, not guide him through an episode of
Dora the Explorer. It can be quite refreshing...
And yes, a Scalemate search will actually reveal the ENTIRE kit number for that old Eduard PE set, not just a mystery portion. But once again,
it was not available when I did that build. Now, on to answering more questions.
A quick Google search gives me multiple responses, all of which indicate commander, gunner, driver and two loaders (five crew). And I think that can be misleading. I'm quite certain it had a crew of five, but I find it difficult to believe they all worked in that tiny space. In a static position, for which that piece was primarily designed, I'd say those two "loaders" were more likely ammo handlers. I'd even venture to say the driver shared in those duties. Position improvement, setting fuzes, stacking ready rounds to be handed up...
It only takes one dude to load a 155, and contrary to what's been posted in this forum in the past, one man
can handle an eight inch round if he's been working out, so two guys to load a 75mm round seems a bit of overkill.
So two in the fighting compartment still seems about right.
