Odds of finding one on the E/pay are truly quite slim, and at best would be a high dollar feeding frenzy for Tron lunatics, that , the shroud, and the black light assembly.., Im not cutting down that Happ stick , seems quite reasonable and a good solid choice. The fact you started with the C/p, will be of benefit since you have the physical size when you try to match it up to the 80% accuracy of those plans you are using, and allow for minor changes....Again good luck, looking forward to seeing this project.
