Differences in the standard injectors

[Dalamar]

I'm sprucing up the inlet manifold area after changing the valley gasket and noticed that I have two kinds of standard injector fitted. Both have the D1830GA marked and I recognise the Lucas logo on one injector but I don't recognise the logo on the other. Both measure out at ~16.5 Ohms and same resistance for all my other injectors that work fine.



Out of curiosity, is there any difference between the two? One newer than the other? I'll be giving these a quick sonication (whilst activating the solenoid), checking for leaks and new o-rings (BS203) before refitting.

Eventually, I hope to go to a newer style injector but for now I want to get back on the road.
