GGs:

I have been cleaning up some saws and came across some with some 
interesting logos. I don't know if they are rare, or valuable so any info 
along these lines will be appreciated.

DISSTON TOWN AND COUNTRY
Wheat handle (apple) has a little town etched on upper right and a barn 
etched on the lower left.

KEYSTONE K-4 AIR MASTER
Wheat handle (apple) has a B-29 (? not great identifying WW2 aircraft).

KEYSTONE K-4 AIR MASTER
Wheat handle (dark) has a Bi-Plane logo.

KEYSTONE K-6 CHALLENGER
Wheat handle (apple) has a Boat logo.

ARISTOCRAT SUPPLEE-BIDDLE HARDWARE CO.
PHILADELPHIA CAST STEEL WARRANTED PATENT GROUND

Any and all information will be greatly appreciated.

                        Thanks
