Type 5A: The diference between this drill and the first No.1 drill with the behind-the-main-gear wiper is rather subtle, as  the side handle is of the Montgomery & Co. Catalog style, and the main handle has the narrow waist of Type 5 (same link as above).

However, the frame is intermediate in design between Type 5 (this link is the other example of that type) and Type 6; compare the inboard spindle housings.  Millers Falls was apparently working to beef up that part of the frame.  The Type 5A design
nevertheless later became more the norm than that of Type 6.

It could also be that they were making room for an internal ball thrust bearing like the one in most of the early No.2's that had the Little RailRoad Car Wheel (LRRCW) side support for the main gear.  Frankly, I've never found a No.1 drill that needed attention to the spindle, and so Ihaven't had the opportunity to  take the spindle out of one of them.  If you decide to try this on your own, don't pull the spindle out until you have put the drill inside a suitable container - the balls will be tiny and quite numerous - something like 1/16th inch diameter, and you will never find very many of them if they fall on the shop floor.

The insert at right confirms the September 29, 1896, patent date of the no-springs chuck, also used in the  Types 4B through 10 drills, even though the stamp has become worn (already ?).
