A very scarce little brass router. This small router is the Sargent No. 73.

This router has two different cutter position slots and is provided with three cutters.

I believe this is the first time we have had one of these and its not on my radar as one we have seen before.

Condition: one of the screws seems very tight, I didn't force it as I didn't want to risk cross-threading the hole - the other screw fits, please see photos for condition.
