TNT are starting to replace their 737 300F's .The ones their chopping in are from GECAS. Some of these aircraft are OK,a few dogs.
Go for a freighter with a Boeing door,Bedek also hold the STC.Couple of the TNT 300F's have partial glass cockpits,but these are QC's so I imagine they'll hang on to them.
Although they haven't been very successful with their pax ops !
