Heavy Duty punches, hand or press operation

Description

HD punches-
Offered is an assortment of die cutting punches for unknown use.  Are of very heavy construction & could be for hand or press use.  Only one piece has an markings which are "C.R.S.  DET. 8.751".  I would say most or maybe all of these have never been used, there are no hit marks on the handles.
1. 4 pcs. with 3 3/4 x 1 1/2" die cut area.
2. One piece with 3 5/8 x 1 11/16" die cut area.
3. Two pieces with 3 1/2" circular diam. cut.
4. Two semi-circular 1 3/4" diam, have different design bodies.
5. A triangular cutter with 1 7/8" height & spread.
6. A 2 1/2" tall circular insert with 1 1/4" ID that doesn't seem to fit any to the punches but was acquired with them.
All of the punches except for the triangular one have foam rubber inserts with some variation in cutting depth.  Cutting edges are sharp & ready to use.  I would give these a tool condition rating of Exc.
