more help with identification
pictured below are more items that i got at a local auction. any help identifying would be much appreciated as well as advice on resale. i have 6 of the ones in the first picture, 3 different sizes. most of them are bolted together on the ends, two are welded. not sure how well the images show the bolts. no manufacturers marks. i have 2 of the keys (?) and around 20 of the other items. thanks in advance for any help or advice.

They look like chases for rubber stamp vulcanizers and Wickersham quoins and a key.
