I thought that odd too,

possibly removed due to step at the top of the bore / wear?

Certainly looks like a lot of combustion blowback deposit build up in that area?

Can't the big ends have (i can never remember which way it goes) over size shells fitted? or is the crank that far gone ?

Sounds odd, but thinking outside the box, could the customers frame be modified to accept an off the shelf refurbed BM unit? providing the drive end is the same

may be a cheaper alternative for them if this is going southbound

Roller bearing crank on this one,
Lubed by a slinger ring iirc,
Small oil pump sends oil into a centrifugal ring which lubes the crank.
They fill up with sludge and then overflow ,no oil to crank bearings.
