Hallo Maurice,
It's a KM built whaler from a Norwegian yard, and she has the tachtical markings of the 57. V-Flottille.
The flotilla had 6 such whalers (built from 1940-1942 / V-5711 - V-5716), but the only construction that fits in is Akers mek. verksted's 500 tons whaler. The flotilla had 3 sisters (V-5713 Tirol, V-5715 Skagerrak and V-5716 Flandern). Flandern had different tachtical marking, so it's V-5713 Tirol (1941) or V-5715 Skagerrak (1942). It's an early outfit, but the painting is different from the 1941 outfit of the flotilla. I think it's probably taken in 1942 or early 1943 before being rearmed and converted during WLZ.
Unfortunatelly I don't have a certain identification of the markings for V-5713 and V-5715.
A better scan had been interesting for checking more details
Best regards,
Erling
