    One should look very good to the photos during april testing, scruteneering and race of 1967. When highly detailed photos are available (LAT or DPPI) you could check the details (even the number of rivets on some panels), they should be different on each car. Each cars has their own particular (tiny) details.
    Everyone already saw the aero-shaped mirrors which were on the car Nr 21 during April testing but not during the race. Maybe they (Ferrari) only have put a new front to the car with those non aero-shaped mirrors........

    Wrong way round, Tom. ;)

    Easy way to tell April Le Mans Test Days photos of the #21 car (apart from the mirrors) from the Le Mans 24 Hrs #21 ....
    .... are the font / size / positioning of the chunkier 'squared-off' style racing numbers used during the April Test Days.

    I found this nice picture of P3 0844 at Monza 1966 while looking through an old magazine today.

    The drivers were Surtees and Parkes, so I imagine this is Mike Parkes, who was quite tall - not much headroom in there!

    There is no photo credit listed.

    Yes, Mike Parkes' height - I think he was 6' 3½" (192 cms), from memory, obviously caused him a few problems in the P3.

    (Though looking at your photo from Monza, again, that could actually be 'Big' John Surtees - note the colour of the lower helmet). ;)

    Here is Mike Parkes in 0846 at the Nurburgring in '66, with his helmet stuck out in the breeze, well above the windshield.

    However, all was solved with the P4's modified pedal box, which allowed him to sit a lot lower ....

    Here's Mike again in 0846, but now as a P3/4 (or the prototype P4, as the press called it at the time) .... and looking a lot happier. :)

    Yes, agreed - even though, IMHO, the P3 is nowhere near as aesthetically pleasing as a P4 - particularly in profile.

    I was scratching my head, trying to remember who to thank for having emailed it to me, at the time I posted it.
    IIRC, now, it was Thomas Horat of http:www.motorsportfriends.com who kindly supplied it (a little while back).

    There is another similar-themed (but a B&W front view) photo, of Mike in 0846 (as a P3) at the Nurburgring, posted on Barchetta:

    Headlights are a little bit more drawn to the bottom. Tail is different between the tail lights and behind the back wheels. The shut lines of it are in line with those from the doors. P4 got highre shutlines. P4 bodywork is a bit tighter.

    Look at post #53 on this thread:
    http://www.ferrarichat.com/forum/showthread.php?t=139128&page=3

    By the way: 412 P is modified P3 with P4 bodywork features. (0844, 0848, 0850, 0854). Those cars have a big bubble in the tail under the perspex window covering the carburettors, and one airscoop in the middle of the nose section instead of two small ones like on P4s.

    Also have a bump within the radiator outlet covering the top of the pedals/master cylinders, which the P4 doesn't have.

    so in effect the cars all now look like P4's with the addition on the 412P's of the single frontal airscoop and the different engine cover ?

    Sorry for the late reply, Nick. Looks like Wouter and Paul M. have already replied with the most salient differences.

    Apart from the differences in the slot vents, in the upper upper lip of the radiator openings, which Wouter mentioned in his post, the actual shape of the radiator inlet is different between a 412P (P3/4) and a ‘pukka’ P4. The lower edge is more curved on a 412P. This is probably best shown by a photo posted by Marcel Massini © in another thread:

    There's a bit more to it than that, Nick ....
    It also depends how original the car's bodywork is (e.g. on 0856) - or alternatively, how many times it has been re-bodied over the years - and how well that was done (e.g. 0844; 0850; 0854 and 0860 all spring to mind).
    You need to spend a lot of time closely studying the (sometimes very) subtle differences.

    Here's a couple of Pierre Bardinon's P4 #0860. Original nose compared to the later repro item that she currently wears. Subtle, eh ? ;)

    Thats very true. Each race they might have had to fix some bodywork. Look at the nose of 0846 at Targa Florio in 1966 when it was still a 330P3. Its so exaggerated I wonder if they pryed it open to let more air through maybe.

    Great thread by the way! Some pics in here I have never seen before.

    Quite possibly, Ed. Look also at the radiator outlet on top of the nose. It appears to have had some extra metalwork added. Something similar was tried earlier, at the P3's first race at Sebring in '66 - except then, it was just an un-painted alloy lip.

    Thanks Paul,
    The one glaring mistake on the model is it didn't run with Firestones during Sebring.

    Of course, the P3's were still running Dunlops, until they switched to Firestones for Spa.
    Looks like #0846 (as a pseudo N.A.R.T. entry) ran on Goodyears at Le Mans in '66 too.

    Going back to earlier questions raised on pages 3 and 4 of this thread, from post #55 through #69:

    …. With apologies for the weeks that have since passed. My contact took 'a little while' to come up with the photo(s) below.

    I have been studying a very high resolution scan of two original B&W photos (a jpeg file of approx 5.6MB measuring 2372x3126 pixels). The bare P4 engine block, shown in them, belongs to the same motor believed to be currently fitted in Lawrence Stroll’s 330P4 #0856.
    By zooming in on this scan of the photos, it is just possible to read the two stampings: 0856 and 237 N 1 ("237" being the 'Tipo' or 'internal engine number' stamped across the top of the flywheel housing).

    What does this prove, or serve, other than to add to the existing confusion ? I’m not exactly sure.

    The factory race diary for #0856 (at Le Mans) states (without mentioning race number allocated):

    However, for the earlier Spa 1000Kms race, it states:
