I will look this evening to see if the codes for the undersides are there ....
If the underside was blue (RLM65) then the codes would have been on the underside of the wings,either GA on one wing and 5K on the other,or just the aircraft letter G on both wings outboard of the balkenkreuz. If the underside was black they'd have been overpainted.
I'm not familiar with this unit so I can only quote common practice!
I've no record of I./KG53 on the Dutch airfields mentioned. They were formed on 9/9/44 at Varrelbusch. The Gruppe was divided with Staffeln at various airfields,1./KG53 at Varelbusch, 2./KG53 at Ahlhorn, 3./KG53 at Vechta.
In December 1944 they moved (retreated?) to Leck with an element (not sure what) at Husum.
II./KG53 and III./KG53 also converted to V-1 launchers operating from Reppen and then Bad Zwischenahn and Shleswig and Griefwald respectively. The re-locations to the North/East were presumably to avoid the advance of the Western allies across the low countries and into Northern Germany.
