Took some more gear to rental storage and after removing the chassis from the TK 35 box tried to remove the strap handle but could not budge it, so took the box back home.
After some struggling managed to remove the strap by a combination of levering and hitting a block of wood against the long securing stud.
After unfolding the edges of the end cap was able to pull the metal strap out of the outer strap surround and also push it back in.
Subtly different from the Grundig straps in this linked Thread because impossible to remove (in-situ) the end caps off the strap because both ends of the end cap are folded over the mounting piece (not that it would have helped).

No access to any welding facility so will look to make a replacement strap. I have just recently thrown away some rusty saws, think they would have been too thick.
Dimensions of the metal strap piece is 15mm x 235mm x 0.55mm
