NICE Panzer 1B!
I really like seeing these done up in the brown-over-gray scheme "regulation" through JUNE 1940! Yours came out nicely.
I'll guess this is the Dragon 6186? kit - their first Pz 1B, and not the slightly modified 6207 "DAK version" (which I am WIP right now) - both suffer that idler issue... You caught that and it looks right!
Alas, NONE of the Dragon 1B kits - not even the most recent Smart Kits with their great (IMHO) MagicTracks and really nicely-done new idlers - have yet to address the very visible details at the outer ends of those wheel-bogie frames (a cast-in pocket with a bolt-head inside - part of the assemble process for the real tank and actually only even feebly-depicted on the old Italeri kit, which has a little bump there for that bolt-head)... But this is no gig to you!
Your build looks really cool, even if pretty darned "clean"!
My one "carp" is those small number plates... your numbers are too large for the plates, and generally those were white on black... but that's only a "generally".! Few put these on their builds, and they were a really common feature on Poland and France-campaign tanks. Kudos to you!
