A genuine original Triumph oil pressure release valve for a 1937/8 speed twin.

In as found condition

The end has been machined in the past and probably for some damage on the end.

Not tested so sold as spares or repair but the machining should not make a difference on working just making it a bit more difficult to fit a filter gauze on the end of you wanted to.

Still a rare item.

Will need checking on a pressure set up to test the release spring

I have added a pic of another to show the end without the machining.

Obviously the sale is ONLY for ONE
