There are actually two different HOB T-6's. One is their 44" span and the other is about a 31" span. The plans that were a freebe from HOB were for a Ziroli ( sorry if I misspelled) design not the same as the HOB. I have a set of the 44" HOB plans but I have made some penciled in changes to try to round out the fuse for a more scale like look. Wattmeter may be in trouble in contacting HOB, it seems questionable as to whether they are still in busness or not. I also have a copy of the Ziroli T-6 MAN plans. This plane comes in at approx. 31" wing span. Mr Ziroli has been qouted as saying that MAN errored in reproducing the plans and that for the actual design scale the builder should enlarge them 5%. Last I heard he still offers the canopy and the cowl but they only fit if you enlarge the 5% mentioned.
Wattmeter, are you looking to scratch build the HOB version? If you are interested in a kit I know that as of 2/13/09 Andy's Hobby Towne in Baton Rouge, LA had two of the 44" and one of the smaller 30ish inch kits in stock. If you are looking to scratch build the 44" be aware that the HOB plans DO NOT include the wing frame patterns in the drawnings. You would need to outline the frames from the kit balsa sheet. The MAN plans do have all frames and templates included. If I can help further email me at [email protected] and we can see what help I can be. If you have the HOB 44" kit but lack the plans we can try to arrange getting you a copy from my set.
