Help to authenticate glassware for 1912 England

[Carol O]

Just volunteered to be the "props manager" on a local production of "An Inspector Calls" (English farce circa 1912). Props list calls for glasses for port, sherry and whiskey. What would those glasses look like? Where can I get information (pictures, etc.)? What liquid mixtures would I use to substitute for the actors having to drink the port and the sherry?
