Interesting prototypical '4-link' coupler there!! Was the rear coupler the same, did you happen to notice?
I've noted on threads on RMweb that the Dapol 7mm Terrier in particular seems to suffer from buffer locking on tight curves, especially at the rear due to the long overhang from axle to buffer beam. I wonder if the real thing suffered from a similar issue.?
This is a standard SR three shackle coupling fitted from the 1940s to many SR locos classes still in service.
They may have well sufferd from buffer locking - except the answer was to carry an extra three link coupler on the hook to gain the extra reach for shunting in a similar fashion as the SR US tanks (USATC S160) did around Southampton docks.
