an unnumbered 214 mount with round edges and phosphated bands is correct for this scope. I have seen and documented one of the few original combinations.
it is true that nearly nothing is known about those ZF43/1 scopes but Nigromontanus from Austria has got an original ZF43/1 with its original waa214 mount.
I have seen an other ZF43/1 scope with its original Waa214 mount as well. This other scope is belonging to a fellow sniper collector in France.
Just observations. no certainties. But It can help.
