Lauritz BRANDT worked in NYC circa 1855. Most NYC planes are not dovetailed but cast iron. BRANDT and TOLNER, both early makers, dovetailed their planes.

In the mid to late 1800s there were a group of machinist planemakers who must have studied the same material as their planes were very similar. These men were:
Napoleon Erlandsen & son Julius, father and son, worked in NY 1865-1935.
Lauritz BRANDT (1808-1887) working 1842,
Charles TOLLNER worked in NYC circa 1851-61.,
Joseph POPPING worked in NYC 1884-1895.
George THORESTED worked in NYC 1856-59.
Knorr & Mantz probably worked in NYC 1880-90.
These NYC planes, especially the miter planes were quite similar.
some were dovetailed but most were cast iron, all with adjustable throat plates.
They are characterized by their rosewood buns affixed to the iron.
