NorthStar Horizon Case Cover Replacements

Hi, I noticed in another cctech mailing list thread about the NorthStar Horizon case cover replacements. Recently, I procured a NorthStar Horizon which is missing its original wooden case cover and I was looking to either buy an original replacement or make a new one. I did not get a lot of responses to my queries on other forums for a replacement wooden case cover so I am considering fabricating my own. Apparently, it is common for Horizons to have lost their wooden covers over time for many reasons and others have done what I am considering. Has anyone built replacement NorthStar Horizon case covers before and would be willing to build more? They do not look terribly sophisticated to build provided you have access to a table saw and the proper bits. I was planning on just copying the dimensions from another Horizon wooden case cover I already have. If anyone has a spare NorthStar Horizon wooden case cover, has built new ones, or knows how to build a replacement, I would certainly like to hear Thank you in advance. Andrew Lynch
