7 graduated center bits and 4 screwdriver & countersinks are stamped 'PRESTON & CO'.
1 extra large countersink stamped 'BUCK & RYAN CO.'
10 spoon and nosing bits are unmarked.
2 square and half-round reamer bits are also unmarked.
All are in very fine, little used condition and exactly as found. As comprehensive and lovely a set as I have ever owned. The perfectly fitted heavy red felt case buttons and rolls up for convenient storage. Top shelf.
