Scot ReaderTed,
I think the only one I have ever owned is Tannehill (No "L") with Sov 460.
By the way, perusing Bill Brown's superset spreadsheet I noticed that Art Martineau has Cobb Red with a Sovereign 460 back--although since Art has been working on a complete T206 Tigers front/back set for years I seriously doubt you could get him to part with it.
