Getting back in it

Based on the lack of swing arms on the suspension I would guess that this particular Hanomag is a reissue of a much earlier kit. Tamiya's more modern offerings have significantly more detail and are more accurate. It took them a while, but they eventually figured out that their customers were no longer kids, but rather grown men that demanded more from a kit than they'd been offering. This lead to a plethora of newly tooled outstanding kits that raised their status among modelers considerably.

Panzer grey is an excellent choice for an early halftrack like this one, but I'd like to suggest that you invest in an airbrush. It will completely revolutionize the way you paint and weather your models and leave you wondering how you ever got by without one. You're already doing work at a higher level than many modelers, which makes me believe you could put an airbrush to really good use.
