Manual for B&D Router # 7620

Before my father died late last year, he gave me his Black & Decker, 1 HP Commercial HD Router No. 7620, Type 1, RPM 19,000, Volts 120 AC, Amps 5.5, U.S. Patent Nos. 2,855,963 3,302,047.

Unfortunately, he no longer had the owner's manual. Does anyone know of a source? The Black & Decker people didn't have one. I'd like to be able to download one in PDF format.

I would be grateful to hear from you.
