Some further questions to your superb explanations:
Do you also know how many DCs the two Thornycrofts of the Grom had?
20 like the Wicher? I model the early DCTs which you arenīt sure if they were on board with two Thornycroft Mk.I with 10 DCs each.
Do you know where the single launcher on the Wicher was positioned and if it was a K- or Y-Gun.
Are you sure, that the have used the Thornycroft Mk.IV until the end of the war and havenīt upgraded to the Thornycroft Mk.V?
Thanks in Advance mate
