It sounds like a quince (Chaenomeles species). Here is a link that might be useful: Flowering quince

True that 'Kanzan' is one of the more vigorous cherries, but virtually all will get larger than you want. The only commonly grown one that doesn't, 'Cheal's Weeping', is in my experience, very prone to disease and dieback and usually doesn't look very nice. Might be better to try something other than a cherry, such as some of the Chaenomeles quinces, which are generally fairly small shrubs inside your size limits. PS spellcheck: 'Kanzan'. The 'w' is an all-too-common nurserymans' error. Resin
