Input on rebuilt 850 - odd part number

[Ekliptix]

Wow, I don't think I've been on here in a decade!

I'm looking at a 2017 850 on Saturday. 4,000km but with a new engine, still in break in mode. Good price on the sled.
I have a copy of the dealer invoice from the new motor install. The PN listed is 421000726 - Short block 850R e-tec Rebuilt.

What I'm curious about is what year the short block parts are from? Google doesn't yield much for this PN.

Anyone have any insight to what this short block year could be?

Thanks - Graham

Here's a pic of me riding my brother's 850 to contribute something more fun to the thread.
