M-25/XP, Kubota D-850/950 block serial number location?

[KWKloeber]

Mates and Mate-ettes,

Has anyone positively put their eyes on the location of the Kubota (NOT Universal) engine serial number on an M-25 or -XP a/k/a/ D850/D950 blocks? 
The Kubota label that's supposedly on the valve cover is gone, or was removed by Universal. 

I have the Universal s/n, but am looking for the Kubota s/n, and haven't located it using the Kb s/n location diagrams -- nothing by the injector pump, etc.  Not sure if the 850/950 block is a Kubota "super mini series" or a "-03 series" engine - anyone know?

Contrary to some popular belief, the dipstick number is not the s/n.

Thanks,
Ken K

Ken : The Kubota stamp is on the block just on the edge of where the injection pump mates to the block. 

Your timing shims may be covering the stamping!?!

Thanks Ron,

On the vertical face, I presume?  I will have to do some more searching/paint scraping!

Ken : NO, the stamping is on horizontal surface!!

Interesting. But none of the 4 are our engine numbers.
Our D850s/D950s appear to be like the second block (located on the injection pump land) but does anyone know bout the 35 and the B series engines?
