633i service book found in my newly acquired 635csi highline

[Hoarder]

Bit of a long shot I know but I have recently taken delivery of my Zinnober 635csi highline and within the paperwork was an old service booklet for a BMW 633csi
Just thought I would post it up on here as it could be the 6 is still alive and the owner is on here.

Would be nice to reunite the 633 with it's original service booklet.

Date of registration
11th January 1977

The reg 124DON is now registered on a BMW 3 series.

Going of the Vin this could be no 4 633csiA RHD of the production line, would be amazing if it still exists.

Thank you
