[meteorite-list] Collection numbering inquiry

[Dave Gheesling]

Hello All,

Might anyone be familiar with either or both of the specimen numbering
applications (i.e. what collections they might have been associated with) in
the second image below?

Trying to research some intermediate provenance on this piece, and any
insight would be much appreciated.

Thank you, and all best,
