Gauge blocks, micrometers and gauges: protect matched sets

Keep a matched measuring set together until its contents have been checked. Mixing loose gauges into a fitted case can make the sale look more complete while destroying the record of what belongs there.
Start with the case, its identifier and any contents list. Then record the instruments actually present. Preserve separate identifiers where available, and do not assume that a case label identifies every item inside it.
Use three inventory groups
| Group | What belongs in it | Record to make |
|---|---|---|
| Matched set | Items connected by a reliable contents list or other evidence | Expected contents, actual contents and missing positions |
| Identified loose instrument | Readable individual identity without a demonstrated set connection | Manufacturer, model, markings and available documents |
| Unresolved item | Identity or set membership not established | Photograph, current location and question to resolve |
For each set, mark missing, substituted or uncertain pieces explicitly. Record dimensions or ranges from reliable markings and documents, without converting an unreadable item into a guessed size.
A photograph of a closed case adds little to this exercise. Obtain a clear contents image and detail views that connect the record with the actual instruments. Avoid moving delicate equipment unnecessarily for presentation; seek suitable handling advice where needed.
Match the measurement records
Attach available calibration documents to the identities they actually cover. Preserve the complete scope and reported findings. A report for one instrument should not become “calibrated set” unless it genuinely covers the set being described.
The torque-wrench certificate guide explains the document-matching distinction. UKAS's metrology information provides context on accreditation in measurement services. Neither a laboratory name nor a recent date removes the need to match scope, identity and later history.
Record known repairs, damage, storage changes and use since the report. Do not promise a universal remaining calibration period or guaranteed accuracy. Questions about present measurement suitability need an appropriate specialist.
Compare groupings without losing the sets
Use the workshop lotting worksheet to compare complete sets, identified loose instruments and wider groups. Estimate the sorting effort for each option without splitting matched sets merely to increase the lot count.
A wider metrology sale may include a coordinate-measuring machine or an optical comparator. Give those machines their own records and keep small gauges identifiable when deciding whether they form useful accompanying lots.
Send UK Auction Group the three-group inventory, completeness checks and matched reports. Identify the sets you want kept together, and ask for a lotting recommendation before separating their cases or reallocating individual pieces.
