Maintenance troubleshooting letter A through H kit in hard carrying case looks like it has all the letters that could fit in each one of the little containers has glue cleaner wire brush in applicator brush with bottle the bottle of the solvent is half the three quarters full has one other little container with extra letters in it I don't know what that the glue is any good but that's not hard to come by the case locks and I have a key with a spare key the case is 12 in tall and 16 inch and a quarter wide and 5 inches thick case appears to be in great shape this came from the government maintenance. I doesn't appear that it was used any questions please email. I 've got some two part Lock tite epoxcy glue I will throw in a new tube with was about 20.00 so you can get right to installing letters. I know its good stuff a guy got a few and used them to put tiles on the ceiling of his shower not what I would use but to each as own and they stayed cause he came back for another tube to finish. Thanks for looking
