Fowler boiler fitting

[oneday]

Hello,

Im looking for a boiler backhead fitting that is missing from my 7nhp compound. This is the fitting that bolts to the steam collecting point just below and between the 2 top gauge fittings.

I think it has a lug on one side that bolts through the cast iron tray that runs across the back of the boiler and provides a steam supply for the injector on the left and the water lifter on the right. Im afraid I don't know what Fowler calls it but I expect someone will know.

Does anyone have a fitting, un-machined casting or pattern please

Thanks,

Mike.
