WTD: CTC Choke Info

[KA8WTK]

Looking for data on a Chicago Transformer choke. The only markings are the "CTC" stamp on the side and "7282-B" on the bottom. The 7282-B does not appear to be a CTC part number in the 1953 or 1958 catalog, so it may be a military or OEM number.

Thanks!

Additional information: This choke stands 6" tall and is 4.75" X 5" (length x width). The terminals are on top. (They look small) There is a "flange" on either side for mounting on a flat surface.
