Subject:Hammond key sizes...?

I just put my SK1 and XK1 next to each other and I noticed that the keys
on the SK1 are noticeably larger than the keys on the XK1 making the 5
octave keyboard of the SK1 significantly longer than that of the XK1.
What gives? Which is closer to the size of the keys of a B3 - or did
different B3's have different size keys over the years?
