New Old Tools, Potd, And What Is This?

[T Bredehoft]

A is either an automatic center punch or part of a trammel
B (band letter under C) is a part stop for a mill, as is I.
C is a tool maker's clamp
D is a centering square, put it on a scale (1" by 1/8 by 12 or longer) find center on round or square ends of bars.
E joins two scales at 90º.
F Joint to scales end to end
G are riffle (not rifle) files for mold makers, generally
H two scribes
I part stop for a mill.
J is a primitive indicator
K may be a trammel, but made up of various pieces

I can't see/identify most of the other pieces.

G are checkering files used for metal checkering. Sorry, they weren't supposed to be in there.
