Hi Mike,
thanks for sharing this photo - not the usual Fw 190, that's for sure
The high tactical number normally indicates a training unit, but unfortunately none of those were ever stationed at Nordholz or even in the closer vicinity. However, if you look farther, some of the more northern-based training units, like SG 104 or JG 102, could have been the parent units of our bird, but that's pure speculation on my part!
Regards,
Christian
