Thanks LJ s for the thoughts and opinions.
I went out to the shop last night with the intention of beginning disassembly to try & determine where the malfunction was. One item not mentioned in my OP was that the plastic nose piece fractured and broke off shortly before it stopped shooting. I figured it as inconsequential as it s just there to minimize denting. Working backwards I went from the safety, to the depth arm and then to the trigger. Part #20 in the diagram above shows the little piece of black metal which is contained inside the U shaped metal piece of the trigger. It appears that my frequent oiling and residual build up of dust and debris, somehow managed to get this piece of metal stuck into the “unsafe” position and would not allow the trigger to fire. After a bit of jiggling I heard a click and then voila it was firing again. I liberally sprayed the mech out with WD40 and blasted it from the compressor and all is well.

Had I not thought to come here to cast the question and seek advice I s likely already have the part on the way, many thanks to you all for the “Stop & Think” help!

For future reference the “bumper” is #120 on your parts diagram. Like someone else mentioned, mine also disintegrated (almost like it was eaten by the oil). Also for future reference, if you ever rebuild it, DO NOT remove the top part with the air exhaust deflector. It incorporates a tiny ball and spring and some idiot spent hours looking for that little ball when it shot out of the gun. The shroud can stay on.
