Roy Toy Log Building Set #9 "The Camp" made in U.S.A. Lincoln Logs Plz Read

Roy Toy Log Building Set #9 "The Camp" Factory Sealed Box made in U.S.A.. Missing a single ‘I’ piece -_- I know. Anyway, would be great as extra pieces to add to your set. I played with Lincoln logs as a kid and to me they seem compatible. But I don’t have and LLs here to really test it on. Pieces are in great condition, box is great and even has original instructions although they are torn clean in half… Please, as always, double check the photos. If you have any questions, need more measurements or photos - I am just a message away and always happy to help. I typically make a post office trip daily in the AM every day except Sunday (and days the PO is closed) ^_^ Thank you for considering my item!
