So, not certain it is even a Jag but hoping I could lean on the shared expertise and experience -
Looks like a mk IX to me. Are there ports on the bottom for auxiliary enrichment device (hisser) plumbing?
Look very close for a part number cast on it, ie C2198
All the Jag inlet manifolds I have seen have embossed part numbers
Also very similar to 3.4 Mk 1 if it has single input port on underside for ASC… Mk 2s used multiple (6?) ports.
Spot on - C12438 - looks like 4 hisser ports and it fits a variety of Jags - thanks everyone! FYI - doesn’t fit mine so another item to eliminate from inventory
Those are water ports. They mate to a water rail:
