Sorry folks, I haven't been keeping up with the posting, and haven't done much to the kit either. I've got the wheels looking pretty much as I wanted:
I was going to
airbrush some sand colour on the inside of those return rollers, but decided to brush them instead, as it was too difficult to line the little devils up with the circle template.
I've now glued the upper and lower hulls together:
Not a perfect fit, but acceptable.
I'm thinking of leaving the turret hatches open, but
Airfix have put a great big ejector mark right in the centre of each.
A couple of blobs of PPP in there, smoothed off with a wet cotton bus as they're in the middle of the padding.
Also added some more of the sticky-out bits to the turret.
Next up is the bar armour, which is horribly overscale, but there's not much I can do about that. You can see a couple of sections of it in the photo of the hull - those have been thinned quite a lot. There once was a time when I'd have remade them from brass strip and rod, but I haven't the eyesight or dexterity these days...
If anyone's still watching, thanks for your patience!
Pete
