Gone down the normal routes of old cats, Internet, etc, asked friends, no luck. Does any of you good folk recognise this frame. Looks like Marin, but it's got curved seat and chain stays... Alloy, 3 cables on top tube, removable hanger. Frame number is "AF" then 8 numbers. Its light and the numbers are hand stamped as they are not all that straight. Its pre disc, gut says late 90's. Your sagely utterings much appreciated. Cheers.
