A collection of 9 mortise chisels manufactured by:

Maw & Staley (2)
Mitchell & Co
T Shaw
P Law

Others are unreadable by me.

8 of them have handles, probably originals.

They were owned by Frank Moss, a cabinet maker from Mansfield, Nottinghamshire (1872 to 1952).  I suspect they may have been owned by Robert Moss, his father (1832 to 1894).  One has an owner's name stamped in the handle - G. Illston?

If you need specifics re sizes, or only want one or two I'd be happy to split.
