Pics don't seem to be attached, but assuming you mean Quadura, this is Remo's brand name for their plastic laminate covering on their drums, which is generally higer quality than standard plastic laminates used by most drum manufacturers. Remo have been using Quadura to cover their drums since 1983 to now. Remo generally use quadura to cover their 'acousticon' drums; acousticon being a synthetic shell instead of wood, made by soaking wood-pulp tubes in resins.

So, sorry not much help without pictures. The term "Quadura" gives no clue as to year, model, etc.
