Good stuff so far Andy. Those 'trumpets' are, I believe, the carb and possibly oil cooler intakes.
Looking at the parts fit, if I decide to do a second Gladiator, I think I'll use the old, but still good, Inpact kit, also released under the Pyro, Lifelike and Lindbergh labels. When first released in the mid 1960s, it was way ahead of its time, and even by today's standards, the detail is still pretty good. Built one around 1970, and was impressed at the time.
However, Karl's link (thanks Karl - you da man!) does identify them as the intakes for the oil cooler and cockpit heat. So, that's now solved!
OK, here we go. The first thing I assembled was the cowl which, for some reason, is provided in 3 pieces. One is a full semi-circle and the other two are quarters so why the latter two could not have been made as one piece is beyond me. None of the pieces have locating pins so it's a matter of slip-slidin' the pieces together until they kinda line up. Lining up the parts is not made any easier given that the thicknesses of the mating parts vary. At any rate, here's what I ended up with before tackling the seams:

One reviewer mentioned that he found that the small troughs for the machine guns on the sides of the cowl opening (seen in the pic below) didn't line up with the troughs in the fuselage. Heck, I don't even have those so I'll need to cut these into the plastic once I get everything lined up.

The engine isn't too bad and is made up of 4 major pieces: the cylinder heads, push rods, crank case, and intake pipes. There's a prominent piece that is not featured and that is what I believe to be the oil sump that sits between the lower two cylinders. This, along with some piping, is something that I'll want to add. All of the parts go together reasonably well, though I had trouble fitting the crank case to the push rods as the hole in the former was too small. I ended up having to file down the flange on the push rod assembly and relied on the Tamiya glue to soften everything so that it would press together firmly. Now here's the thing: there is no positive means of locating the crank case relative to the cylinders so you have to carefully eyeball the piece so that the straight part on the top is perpendicular to the vertical axis of the engine. The two intake trumpets were also drilled out - still trying to figure out what these are.

Now, a similar issue occurs when fitting the engine to the firewall. Again there is no positive means of centering the engine so I marked the centers and used my Mk I eyeball to make sure the top cylinder ends up vertical.

The same thing will now happen again with the cowl and I'll need to make sure that everything lines up visually.
With the cowl cured, I started to work on the seams and things are complicated by the amount of detail that one has to avoid removing. The seam I'm working on below runs between the raised rectangular details and you can see that, despite trying to take care with my file, I managed to flatten the high point of one of the cylinder head bulges

Sprue gates are plentiful, often large, and oddly placed. The one below behind the cockpit sits half way on top of a raised panel. Go figure.....

This kit will keep me on my toes.
