1889 Marlin?

[earlgo]

Gentlemen please excuse my bringing up the 1889 firing pin topic again, but I find myself rebuilding a parts gun that is missing the firing pin. I have seen the picture of the one mentioned in the e-bay link and this brings me to the question.
Does the lever bear on the end of the forward cutout (away from the pin tip) to help move the pin back away from the face of the breechblock? It would seem from the picture, no. Then one can assume that the only thing that retracts the firing pin is the "hook" at the striking end of the pin.
Perhaps there were a couple of variations of the pin?
The one I am working with is serial #67950 in 38WCF.
Thank you for whatever information you may have.
