replacement for odd BB

Hi all,

There's a guy on a local site trying to find a replacement BB for his "Gazelle Olympic Race" road bike.
Current BB looks like this:


And sits in a BB shell that's about 39 mm inner diameter. 68 mm width.

What's this version called, and where do you get a replacement?

Other options?

(I think) Ashtabula-to-cartridge won't work. Looks like the wrong diameter.
Ream the BB shell out to take a BB30 press fit?
Scavenge a thin walled BB shell from another steel frame and bond it in there?

Could it be something out of the BMX world?
