At eBay
here there is a photo of a crashed He 111H located at/near Trondheim. No other ID details are provided or visible.
http://www.rafandluftwaffe.info/ suggests that this could be a He111H of 8./KG 26 from Vaernes which crashed on the 5th May 1940 after possible contact with British aircraft. No other information on aircraft or crew are provided.
The amount of snow/ice on the photo might? rule this out.
Any further details on this crash or other suggestions will be much appreciated.
Cheers
Ian
