I haven't seen many Dynamo's on yellow label, does this one look right? 

Tommy Hunt - never love a robin / the biggest man

Styrene with stuck on label, scratched matrix with a signature or plant name something like "Schrowerer" !

Yellow label looks like its got a circular band of black ink around it. Paper seems a bit shoddy which made me suspicious.

Looks the same as my copy.  It came out on Ludix Production records first.

All good. At least 2 pressing plants involved and reruns of pressings with label variations to accommodate a continuous demand like the first example below from the same pressing plant as your yellow one that also had white (demo?) variation... Then the second one here with another catalogue number and flip side as well...
