Seller: jnys2 (1.171) 100%, Location: PLYMOUTH, Devon, Ships to: GB & many other countries, Item: 133094178651 Plato Ansonia, Junghans, Ever Ready Replacement Round Clock Glass. Condition is New. Dispatched via Hermes in a big box with lots of packing. Bespoke manufactured cylinder for repairing aforementioned clocks. I have tried this on a Plato and a Junghans clock with success. I have measured this cylinder for sale as 2.754 diameter by 3.401 high by 0.091 inches thick or 69.95 dia x 86.38 high x 2.30 mm thick. Please accept there will be minor measuring errors. I have others which will be slightly different if yours is not quite the same. Height can easily be reduced, but not increased! The glass is clear and both ends have been cut and and finished very close to the original. Pictures are of almost identical cylinder, but measurements above of the actual item for sale. Hopefully just what you have been looking for!
