Manny,
It looks like the real deal. I confused your bike with a 2nd 753 Perthus I was contacted about out of Hythe, New Forest in the U.K. What are the odds of that?
Whats the serial number under the BB? Does it have the paper sticker on the left chainstay near the BB? Your decals pre-date the scheme in my '88 U.K. catalog by a year or so.
