Stephen.... don't you have a Barnack that was "re-colored" by CRR Luton? While the high dollar price tag that people are willing to pay for a original camera with a little WWII engraving might be gone would it not still be worth $1300?
Nope, no CRRs here. I do have a standard chrome IIIg given a grey hammertone finish by Shintaro.
The OP's IIIC is a pretty camera. At $1300 it will likely find buyers. However that particular camera would likely be worth more today if it still had its original finish.
It would have to be in very poor condition not to be worth more than $1300.
