I tried Hector but he doesn't have any. 

My diesel injection shop said they cleaned and lapped the valve but it continues to drip fuel. Seems OK when pressure is turned up and suggested that I install it / swap into another injector hole in the head.

And it's also an American Bosch fuel pump that feeds these 4 injectors. Two are red; two are yellow so some previous owner has been tinkering with it.

No harm in trying this one and take it from there.

Koo did have some spare bosch he changed  all to the IH

thats why you had trouble in finding it (german owned) bosch was + - '37-42 when IH was forced in house

until recently bosch was easier to get/have made parts for vs IH  and even ( now) NLA   RM/stanadyne

Thanks mmi, that explains a lot of things to me.  Someone has fitted an older engine into this 51 TD9 which has the Bosch fuel pump and corresponding injectors.

I have a quote request to FP Smith but haven't heard back from them.  But the simplest and cheapest plan right now is to get my "cleaned up" injector back and put it in another hole.

Long range (next summer) the plan is to switch this undercarriage onto my 56 TD9-91, pull the engine and possibly change the liners/pistons in the block to upgrade to the 350 motor and fit it into my 56. The head on my TD9-91 is good, IH injectors good and an IH fuel pump so perhaps that head can be bolted onto the 51 (or whatever year it is) block (?)

That's the plan but my wife says I change my mind daily.  🤨
