This is located in the Blacksmith’s Shop at Ferrymead Historic Park, in Christchurch, New Zealand. The shop is a recreated working blacksmith shop – unfortunately they don’t have a blacksmith at present.

It’s mounted too low to be useable, and is missing it’s feed wheel, but otherwise looks complete and in good condition - so good that the maker’s stencil is still mostly legible on the wooden backing board.

The stencil appears to say "WORCESTER MASS USA" "No.2" "BUYNTON PL.." so I've assumed it's a Boynton & Plummer, and it looks very much like another No.2 listed here.

The drill is unusual in a number of aspects. Like Champion drills, the auto-feed arm has a separate bracket that bolts to the main casting. Also, the bore for the flywheel shaft is in a separate, bolt-on casting.

The column is 1 9/16” diameter. Diameter of spindle = 1¼"; large crank gear is unusual in that it has 58 teeth around the perimeter to engage the flywheel gear, but only 38 teeth set at 45° to engage the spindle gear; spindle gear has 26 teeth; flywheel shaft gear has 28 teeth. Drills to the centre of a 15” circle.

Comments: Front view - it's missing the feed wheel and as a result the feed nut and spindle have dropped.
