Abbreviation: federatedp
Products: Model types
Summary:

Federated Purchaser, Inc.; 25 Park Place, New York City - Trade names: Acratest, Acratone, Cathedral Tone. Federated Purchaser was a mail-order outfit. Federated Purchaser has not to be confused with Federated Department Stores, Inc. which did own some stores like Filene's in Boston and Abraham and Straus in Brooklyn.

History:

There's nothing in the 1935 or 1940 Poor's Manual, so it may have been a privately-owned corporation - on contrary of that, the catalog does say "Federated Purchaser, Inc.". Their 1935 catalog shows 8 locations ... Two of these addresses were used by Lafayette in 1961.
