Tony:
Very good question. This 50s/60s era is way out of my normal interests so there are probably resources available that can provide a better answer than what I can dig up. That having been said, I have tried to put together a list based largely on information from Identifying Pattern Glass Reproductions by Jenks, Luna and Reilly. I have provided the original manufacturer's name not the US Glass (Tiffin) reissued name. To my knowledge, these were all made using the original moulds.
15086 Mirror aka Galloway – Punch bowl, cups and underplate
15155 Cromwell aka Knobby Bullsey - Punch bowl, ladle, cups and underplate
15078 Manhattan - Punch bowl, ladle, cups and underplate; salver in various colours (not in the above reference - based on a presentation at 2006 Glass Gathering and a visit to the Tiffin museum)
George Duncan's Sons & Co No. 42 aka Mardi Gras by Duncan Glass (a division of US Glass) - two versions of the punch set in clear and bud vases in milk glass)
Mascotte – apothecary jars in various shapes in clear and various colours, stacking jars clear and stained and maybe milk glass
15119 Palm Beach – by Duncan Glass (a division of US Glass) – bowls, butter, creamer, olive dish, pickle dish, water pitcher, sauce dish, sugar, tumbler vase in milk glass
I am sure there are more but this is a start. I am also sure that we have members who can add to or edit this list.
