Marcos,
Good job on the Skink, but please don't call it a "late" version. There were no "ear'y" or "late" versions. There were only 8 castings made in total and only three vehicles built. All period photos show the turret design with the overhang. Photos of the last two remaining turret castings (both, I think, now in Alberta) show the overhang. Only a set of sketches form the manual show the turret without an overhang and I am sure this was a simplification for the manual, possibly from early turret concepts prior to the incorporation of the Polstens.
While it is pretty unlikely we'll ever find the paperwork to prove it, I'd bet a substantial sum that there was only ever one turret design produced. It's inconcievable that they would have gont to the trouble to make the drawings and patterns for two designs knowing, in advance, that they were only building a very small batch of test vehicles. George Bradford's drawing of an "early" turret are, I believe, in error and I told him so a number of years ago, but this was before the present day photos of the remaining castings surfaced.
You do need to add the spare track brackets on the turret sides.
I'm afraid the markings are a tad off as well. Your markings are for the 1st Hussars of the 2nd Cdn Armoured Brigade (although you are missing the white stripe under the 51 for that unit). While it has never been firmly established exactly who operated the single Skink that saw service, it almost certainly wasn't the 1st Hussars. Given that the Skink toured around the various units of 1st Cdn Army, it's highly likely that it was operated by F squadron of The Elgin Regiment and the markings for that would be "465" in a green over blue square with the 1st Cdn Army sign on the other fender.
