The Lt vz-35 finally arrived and I have to say I'm very happy with it. A slightly grainy texture but not rough and some of the minor problems that rounded surfaces seem to present to 3D printing. That's been fixed with a little light and judicious sanding.
Very clean casting, essentially a two piece item, hull with tracks affixed and separate turret plus separate main gun, hull and co-ax machine guns. Could do with some tools for Czech service so I'll have to dig about in the spares box.
Overall, a really lovely little model, well detailed and requiring minimal clean up. I would highly recommend Mad Bob's models on the basis of this.
Many thanks to all who gave me the steer towards Mad Bob.
