Unknown Clack - poss Foden

[Radhew]

Traction Engine clack valve, of unknown make. I bought this for fitting an injector to my firebox side plates but never used it. It was suggested it might be Foden when I bought it (via Traction Talk) but I have never confirmed this.

The jumper is present. as is the top nut.

2.5" across mounting holes. Bronze body.

I would be interested if you know what make it is, message me please.
£70 outside ebay plus 5.20P&P
