Hi,
I just recieved a 1/35 Bronco Hotchkiss H39 tank that I was able to get for a (hopefully) good price off eBay.
I'm really excited to get this kit, as it comes with interior details such as the driver's seat and controls, the engine, and other drive train components.
As I understand it the H39 Hotchkiss tank was an update to an earlier H35 tank that was initially designed to the same spec as the Renault R35 tank, so that they have alot in common. I believe that a couple of the main differences between the H39 and H35 Hotchkiss tanks were differences in the engine and the fitting of a longer calibre 37mm gun. However, I believe that the H39, H35 and R35 tanks were all designed to fit the same turret, and as such I believe that they should have the same turret ring diameter (though I'm not 100% certain).
As such I went ahead and laid the Hotchkiss and Renault turrets side by side, and upper parts do look as near identical s I can see, as shown below. (Sorry its a little fuzzy, my phone isn't so great with close ups).
Interestingly though, when I compare the turret ring diameter of the Hobby Boss turret to the Bronco turret I find that I can "just fit" the Hobby Boss ring into the Bronco ring, as shown below.
Here the gray parts are from the Bronco H39 model and the beige turret is the Hobby Boss turret. As shown above I can fit the turret ring of the beige turret just within the turret ring of the gray bottom part of the Hotchkiss turret.
As such, it kind of looks like Heller, Hobby Boss, and Bronco may have all used slightly different assumed diameters for their turrets.
