I've only seen a couple of colour pics of the RAFM Me 410 rear cockpit. There doesn't seem to be much in the way of sidewall fittings, so you can probably "wing it".
I was given access to the aircraft a few years back, to get some detail shots of the wheel bays etc for Andy. Unfortunately, the aircraft was under maintenance at the time, and up on jacks, so I couldn't get any interior shots, although I do have a good shot of the front cockpit,taken from a calendar !
