Seems like you`ve got the real stuff there. Either you like it (it functions well)or you upgrade to get a more comfy ride. I wonder if you can find any id? Should be stamped under the BB. I really want to make you aware of how rare those bikes are. For sure, most of them went as export to the US. The US-market wanted something special from MCB to create attention; the stainless! Over here there has been one for sale on the open market the last two years (that I know of).
