I am attempting to compile a time line regarding production of these units. So, I need your help. There are three items I need, but if you can not get all three then anything is helpful. The first (and MOST important) is from the potentiometers- there should be one or two numbers on these. It should look something like this, although the numbers may not be identical: The second is regarding the paint. Does it have the "bird/star" logo at the top? If it does, it should look something like the attachement below. The last is regarding the casing. Is is made from steel or aluminium? Any and all help is appeciated, and any pictures you can send me along with the information would be handy. Please send them to tedintheshed(at)gmail(dot)com. Thanks!
