According to Sandusky customer service, most of the Buddy Products line was discontinued in 2019 and remaining portions were sold to https://www.metalcabinetstore.com/ which may or may not have them.

Page 2 of the Sandusky Lee / Sandusky Buddy catalog indicates that page 52 has File Card Storage Boxes, but the page doesn't exist in this version of the 2020 catalog.

MetalCabinetStore.com carries Tennsco card files, but doesn't seem to have any of the Buddy Products. Apparently they're just a distributor and likely just bought out remaining product from Sandusky rather than taking over manufacturing operations.

Buddy apparently manufactured a relatively wide range of card index files in 3 x 5", 4 x 6", 5 x 8", 6 x 9" formats, they now seem to be discontinued.
