Elmgarden has dated these Victorian Glass Flagon Decanters to the 19th Century.
The decanters have various different cork stoppers, collars, some with pouring spouts and hinged lids in silver-plate.

As to condition, this is generally good the silver-plate is worn on some, and one (a green one) has been repaired with staples, this is very much a lost art nowadays but very interesting to see.
The decanters are 9” tall, 16” wide and 4” deep
