These vintage used cutter heads are designed to fit the Rigby Model D fabric cutters manufactured by J. D. Paulsen DBA Rigby Precision Products in Bridgeton, Maine.
These cutter heads come in various sizes, with each number representing the width of the resulting fabric cut:
#3 - cuts five (5) 3/32" width strips at a time
#4 - cuts four (4) 4/32" width strips at a time
#5 - cuts four (4) 5/32" width strips at a time
#6 - cuts four (4) 6/32" width strips at a time
#7 - cuts three (3) 7/32" width strips at a times
#8 - cuts three (3) 8/32" width strips at a time
Each cutter head also has a matching "cutter finger cleaner" which keeps scraps of fabric from building up between the teeth of the cutter head.
Because these are used cutter heads they are available while supplies last and may contain cosmetic blemishes consistent with age and use.
