Machine-market observation ledger

MBB gives every retained source observation its own identifier, source path, timing and fingerprint—without presenting MBB as the seller or treating source status as a guarantee.

Market Directory / Observation Ledger
14,194 records across 21 sources. These are observations of public source information. They do not establish ownership, authority to sell, physical possession, accuracy, condition, transaction price or continuing availability.

What the ledger records

Each entry contains an MBB-generated record ID, source name and URL, first-observed and last-checked timestamps, observed-field names, source status, a content fingerprint and the corresponding MBB research URL. MBB identifiers are independent and are not the originating site's listing numbers.

How to verify a machine

Open the MBB record, follow its direct source link and confirm the seller's identity, authority, serial number, location, configuration, condition, liens, price and availability. The source controls its current offer. MBB supplies research and provenance, not a transaction or warranty.
