"works" montesa cota

Jared Bates recently sent me some interesting photos of a couple of factory riders' bikes. I had asked him about whether or not Montesa had made "works" bikes. He responded with:

There were no real "works" 247's to speak of. Different barrels and things were tried, but the bikes always looked stock. The 348 works bikes were a different matter! Enclosed is a picture of Francisco Paya with his prototype 348 in Feb of 1974, with different cylinder, head, and carb, also right side shift and exhaust exiting like the regular 247. The rest of the bike was all 247. The other picture is of Malcolm Rathmell's works bike in May of 1975, which bears more of a likeness to the 348 as we know it. Note the offset handlebars and right side shift that Rathmell always used. Also, it still retains the 247 gas tank and older mk1 Amal carb.
