Anyone can identify this ?
if you look on bitsavers under cdc/catalogs
M90310500_Internal_Literature_Catalog_Jul75.pdf
lists several drum storage units including the models 861, 863 and 865
the controller looks a little too early to be for the BG504A
the one you're trying to identify looks to be using 1604/160 series modules
39731700A_BG504A-H_Drum_Memory_CE_Manual_Jul72.pdf for the 1700
