Need original mfr. instructions

Hello, Just got a FOCAL brand (old K-Mart brand, mfr: Maxwell Electronics Ltd.) model# 400 computer bounce type flash unit for film cameras, uncertain vintage (over 20 yrs. ago, say?), on Ebay recently, and would love to have a copy of the original owner's manual that I didn't get with it. While it's a fairly simple older "hot-shoe" flash (slim & narrow, stands up or folds sideways plus an adjustable swivel beam, takes 4 AA batteries) and has just a basic "auto" plus "manual" mode(s), I would like the manufacturer's recommended settings to have on hand for use. Can send you a few quick pics of the unit if needed, if you supply an e-mail address. Any help with this you could give would be greatly appreciated. Thanks!
