Here we have an MTP Smock size 190/112 which is better suited for a taller person with a XXL Chest. 
This smock has been tailored to resemble the Para Smock. 
This process includes the removal of the original  skocks hood, the removal of the flat that covers the main zip, the pockets have been made into Press stud fasteners, the cuffs have been elasticated, and there’s an added flap at the back that fastens to the front of a jacket to stop it riding up during a parachute jump. 
The jacket is in really good condition. 
It’s the only one I have so you’d be buying the one in the photo and I cannot get any other size.
