I can't tell you definitively on the head badge and swing tube decals, the full length chainguard was only on very early models. The majority of the bikes used a chain ring. I believe there are aftermarket chain rings that fit ten speeds and BMX bikes that can be adapted....The whole bike was assembled with standard aftermarket rims, kickstands, hubs, etc from what I can figure out. I haven't seen the chainwheels around on anything yet but I haven't looked.
