Trying to ID a rocket carrying Typhoon lost Feb 1945

[Niederrhein 01]

Sean, my apologies after thinking about your comments of the Serial Numbers being the Aircraft Code I have come to the conclusion that JR375 P2 was originally one of the port cannon installed to that aircraft.
But none of the 609 Typhoons match this loss, let me put another theory on the thread. 183 squadron and 609 squadron were using the same airfields from Sep 1944 until way into 1945. Could there have been a common armoury for the whole of 84 Wing, including 164 and 198 squadrons and theoretically when a Second Serial Number JR315 S2 was to be included would this not enhance this theory als JR315 belonged to 198 squadron.
What so you think?
