Colorado, 74x, 75x and 77x are all 7.5" Hamilton units.  The bulk of the components in these units are the same throughout the different series.

The single stage units (Colorado-single, 741, 751, 771) all originally came with a 1" shaft\ bearing\blade-bore.  The multistage units came with a 1.25" shaft\bearing\blade-bore.  Some of the single stage units were extended to two stage with a longer (non-standard) 1" shaft and two blades with 1" bores.
