@RussellHill,
We saw your other posts & responded on another site; welcome to this forum as well. Parallelmotion who is a member of both forums helped you as well.
From the pictures of your 4147/9, I can tell you that it’s a 100% authentic & in great shape. The pump on the 4147/9 is the same as the pump on the iconic horizontal 4149. Only the 4147/11 has the round pump & working governor; some of these were restored using the wrong pump from a 4149 donor engine.
I am talking from experience as I own a 4147/9 & /11 and since you mentioned the 4159, I can tell you that I also own a 4159/7 & /11 in my collection.
I think you ended up with an excellent engine from Germany for a very good price; congratulations.
