The 16 seems to be every where; I think it should be perked somewhat. How much combat did they really see?
Easy one to answer -
Apart from the .50 cals the XVI is identical to a Mid 1943 LF IX, and identical to a mid 1944 LF IXe.
Assuming they haven't updated the XVI to the correct Merlin 266 FM and still use the Merlin 66 FM.
So 2+ years as an LF IX, and 1 year as an LF IXe / XVI.
Many of us have wondered if there would be as many complaints about the XVI if it had been tagged instead as an LF.IXe
