Court of Appeals for the Eighth Circuit June 5, 1975, 74-1419 (Stewart-Decatur Security Systems, Inc. v. Von Weise Gear Company)

WEBSTER, Circuit Judge.

In this appeal we consider whether, in a contract for the sale of goods, an approved prototype may displace an inconsistent specification in a written purchase order.

Appellant Stewart-Decatur Security Systems, Inc., manufactures jail doors for use in penal institutions. A small electric gear motor is employed to open and close the doors automatically.
