Well the item on the right is a card gauge for 96 column punch card used to check that the card punch is punching the holes in the right place. The 96 column card used a 6 bit character code punched in 3 rows of 32 columns. For binary data such as program cards, the first six bits of a byte where punched in the one of the top two rows and the remaining two bit for each row was punched in the bottom row.

The item on the left appears to be a manual punch for something like paper tape, is there a part number or other identifying marks on it? On the right side of it there appears to be an exit chute and wear on it might suggest it fit into something else.

Thanks Paul. Yeah, I recognized the 96-column card gauge on the right (I've got one). The pic is from an Ebay auction and the seller seems to think the item on the left is for punching a 96-column card, but I don't think so from the picture. I agree with you, I think the item on the left fits into another machine that inputs paper tape, and the big gray button is probably to release the item from the other machine. The seller did not post pictures of the four other sides, that might help identify it.
