* Change 3 Part Black {4275 Hinge Plate 1 x 2 with 3 Fingers (Undetermined Type) to 4275b Hinge Plate 1 x 2 with 3 Fingers - Hollow Studs}
I can confirm this as I have the same variant. I own this set since the early
nineties and it is still in its original box. It is very unlikely that the parts
have ever been mixed with other sets.
