This project stalled in summer 2010, for family health reasons; but I have finally found the motivation to restart.
The build started out conventionally enough, but I thought I'd try a bit of interior detail..... at first just the crew compartment. Panzer Tracts has a couple of interior shots, and some Pz1 sectional drawings, and I obtained a very useful set of interior photos from Bovington Tank Museum.
Then I came across the 'Great Wall' engine kits....and the Maybach HL42 had enough useable parts to begin a detailed engine compartment as well. Again, Panzer Tracts was very useful.
All the research, adapting kit parts, and serious scratch-building makes progress rather slow, but very satisfying.
The photos show where I've got to so far.... I'll post more as things start to happen.
