    Peter Coltrin took pictures of the early version of Urraco Bob with XWX tyres in September 1973. The later pictures with P7s and wing were taken in March 1975. Bravo was launched at Turin in November 1974. So I wonder which P7s came first.....

    good point ivor. did you notice any archive photos of the car in between the 1st xwx and 3rd revision of the with the winged brake ducted spoiler the Rob de la Rive Box book show an interim version with the smaller fronts spoiler and no rear wing along with P7. i wonder when that took place.

    this is interesting since if campy did provide the wheels for the bravo before the rallye in mk2 development it would have made it unnecessary for the P7 tires to be stretch over the much too wide 12 inch wheels poached of the jota. they could have used the existing hub without fabricating new ones. for reference, i believe the tires on urraco rallye and the bravo were originally 275/15 (ive forget the profile) same size despite whats been printed lately that the bravo came with 285 silhouette size tires. today thats what they have one the both cars I seem to recall.

    many thanks for posting the gearbox pic...

    Reading again JF Marchet's Urraco book, he wrote Urraco Rally was fitted with 2.4 engine in begining. So, Bob Wallace played with a small engine... because later JFM wrote : "by the time Bob Wallace left Lamborghini it had acquired a full 3-litre, 4-valve, dry sump engine, coupled to a six speed gearbox.... peak power was in excess of 310 bhp."

    Witness of that era I trust JFM's writings, leading me to believe it became a real "R&D" car (after being Bob's toy) fitted with the 3-litre 4-valve engine, coupled to a six speed gearbox...

    2 years ago, when I showed Bob the below pic, he stopped talking for 4 seconds... he did the same for Jota & Jarama Special

    Sorry but I don't have those interim pics.

    If Bravo wheels had been available, presumably Bob Wallace would have used them rather than having to modify the hubs to fit the Jota style wheels, though it is just conceivable that Bertone was simply keeping the design under wraps until Turin. The P300 was also launched at Turin 1974 so it is a prety safe bet that the P7s on the P300 based Yellow Mule came later still.

    there isnt much to dispute JFM writings. the urraco rallye began with a 2.4 because thats what its started out as...one of the pre-production high headlamp prototypes. Which one ? im not still exactly sure.

    As we know Urraco bob wasnt build from ground up.it was an experiment car of course research the latest in racing technology and how it may be applied to the road cars. but it didnt ever ran a real classified race in gr4 , though bob did claim racing at misano it as written in various books.

    the 2 or 3 modified urracos running around with add on flares and bravos were the true development cars. one eventually with the possibility to become the snorkel silhouette itself i reckon.

    In 73 with the production cars rolling off the lines, wouldnt this make much more sense to use production body shell for R&D if the parts were to be translated to the road cars themselves while transforming the proto into urraco bob rallye from an old auto saloon car?

    ivor, i too think the yellow test mule came later than 74 since it was based on a P111 type body shell. but remember there are 2 other cars at the factory running with P7 also besides the rallye and bravo.

    my comment was not to dispute JFM writing.

    I meant to clarify the fact : Urraco Bob wasn't fitted with 3litre-4Valve engine when Bob Wallace was driving/playing with it...

    so the readers can understand the chronology of that car, as a Wallace's toy at 1st and then when Bob left the factory, it became a "R&D" car with 4valves engine & 6 speed gearbox.

    do we know for certain wallace didnt play with the 4valve motor especially when one of the 4 valve motor shown in pictures had belt driven heads? the chain driven P300 motor was unveiled in torino in 74 and developed before then since it was a production model.

    i myself being asking the very question for long while.

    If "JFM's writings are to be trusted" we should believe that "by the time Bob Wallace left Lamborghini [ie BEFORE he left Lamborghini] it had acquired a full 3-litre, 4-valve, dry sump engine, coupled to a six speed gearbox....

    You were right, Wallace tested the 3 litre 4-valve engine, but it was not yet coupled to the 6 speed gearbox !

    In fact, chronologically Urraco Bob was fitted with standard 2.5 engine, then 3.0 standard and later the 4-valves.

    I've read in another Forum about FJB ltd, Jeff Leblond who was preparing a specific engine lid with louvers to fit Jalpa.

    Like me, he was also thinking to increase intake distance as well as evacuating hot air, like for Miura ...

    Love the text to the last picture:
    “1985 LAMBORGHINI JALPO 3 CONVERTIBLE ( ITS NOT A MUCEILGAI)???? ITS A JALPO 3 CONVERTIBLE”

    It looks great though.

    No way this thing fetches $37k. Much nicer examples are lucky to fetch mid-thirties. My guess would be high-twenties, low-thirties.
