Hi, All!
I'd echo some of the previous: The CH SIG 33 auf Pz. III kit is, IMO, a pretty nice kit. It's the best styrene 1/35 available of this very cool (ugly, too) beast - to-date (OK, also the only one, being it's the old DML kit with added figs, Magics and maybe a little PE?). I found the mentioned Osprey book and its build to be nothing less than really inspirational - I got the book and... hauled out and got this kit, just because of this!
I think it's a good kit that asks for a few tweaks to become great. The Osprey lay-out shows quite a bit of detailing and mods - I'm going a much - simplified route; I'm replacing those somewhat lacking road wheels with some from a current Dragon PZ III kit (turns out that the recent Pz. III E "France" kit comes with a set of extra road-wheels... how handy! - providing you have that kit...). New wheels with those little reinforcement posts and good depiction of the rim-welds will really compliment the kit's Magic Tracks. Adding on that second box and some deck stowage are also on my list. I'm thinking maybe just a bit of detailing front and back (chains on tow-eye pins, spare road-wheels per the known photos, heat-shield / deflector over the exhausts, a nice tow-cable, and carefully square or sharpen the edges around the barrel-muzzle), and it'll be a nice addition to the shelf.
Of course... now that folks are talking about building this thing... Mr. Dragon will soon start on a modern SmartKit of it. I figure each old DML kit which becomes one of these CH orange-box "value" re-releases is a toe-in-water test leading to new kit... - Consider the Jagdpanzer IV L/70 (V), then the L/70 (A)... I expect we'll soon see a late-production "Brummbar" pop up (OK, 2 kits - first w/o zimm, followed soon by 1 with) - and, of course, a nice new SIG 33! Build these old things while you can!
Really looking forward to seeing your beast come together and appear here!
Bob
