The Boston No.1 plane?

So I managed to get hold of one of  “small” block planes from “The Boston” – it has no markings, so I’m going to say its a No.1. Although it’s not really that small, in fact at nearly 7″ in length, it’s the same length as both their other planes, the No.2 and the No.2A. The oddest thing about this block plane is the bedding angle of the blade – which at 50º (York Pitch), is almost unheard of in block planes (until recently when companies like Lee Valley started producing optional high pitch blades). The blade is also bevel down. So maybe it’s not a block plane? But what sort of a bench plane looks like this?

The plane feels sturdy, despite being made of aluminum. It has a number of unique features. The first is a finger “tab” in the toe of the plane, replacing what would normally be a small circular finger depression. But to be honest, maybe the plane is more of a two-handed experience, with thumb and forefinger pinching the tab.

The second feature is that whilst the blade is held in position by a fitted lever cap and cross-brace, pressure  is provided from under the blade by means of a machine-screw. As the bolt is screwed in, it forces the blade-assembly up against the cross-brace, holding it rigid. This makes it somewhat tricky to set the blade, but it is a unique way of securing the blade.

Note that the blade set screw is askew. Such work may be indicative of the low-cost nature of these planes, despite their interesting lines.
