Calibration equipment standards come in two very different shapes: a 23-piece used lot of assorted gage blocks and inspection gear, and a single new-open-box calibration probe. The first is a broad collection listed by M & J Tooling LLC; the second is a named instrument with the model C23196-1. Your choice is really about whether you want many pieces or one specific probe.
Quick verdict
If you want variety in a single purchase, the 23-piece lot is the volume play. If you want a clearly identified calibration probe that is new-open-box, the Stock Equipment C23196-1 is the targeted play. The probe's listed price is $8.99 lower than the lot's listed price.
Side-by-side comparison
| Product | Listed Price | Price Bar | Condition | Key Detail |
|---|---|---|---|---|
| 23pcs LOT OF MISC. GAGE BLOCKS & OTHER INSPECTION / CALIBRATION EQUIPMENT | $49.99 | Used | 23 pieces of gage blocks and inspection equipment | |

Where each product wins
The lot wins when you need several gage blocks or a mix of calibration tools. It is a 23-piece package, so you are not locked into one function. The listing says you are purchasing the pictured items, and the pictures are the main source for size and labeling details on these used pieces.
The probe wins when you need a precise, identifiable instrument. It carries the model number C23196-1 as well as the MPN C23196-1, and its condition is listed as New - Open box. That means you are getting a new probe without the unopened package.
Product notes
23pcs LOT OF MISC. GAGE BLOCKS & OTHER INSPECTION / CALIBRATION EQUIPMENT
This lot is the volume option. You get 23 separate pieces, which is a meaningful number if you are building out a calibration workspace or just want a handful of extra gage blocks. The listing comes from M & J Tooling LLC in Dayton, Ohio, and the description says you are purchasing the pictured items, with size and labeling details to be seen in the pictures. The clear trade-off is the Used condition: you are buying pre-owned pieces, and the exact mix is defined by the photos rather than a text list. If you are comfortable reviewing photographs and working with assorted secondhand inspection gear, this 23-piece lot gives you the most pieces to sort through.
Stock Equipment C23196-1 Calibration Probe
This probe is the specificity play. It is a single instrument, but a clearly named one: the Stock Equipment C23196-1, with the same number appearing as the model and MPN. The condition is listed as New - Open box, so the probe itself is described as new while the package is open. If your work calls for the C23196-1, this listing gives you a direct match without the need to sort through extra pieces. The limitation is scope: this listing centers on one probe, so it suits a targeted replacement or a specific application more than a broad kit-building project.
Final choice by use case
- Choose the 23-piece gage block lot if you want to expand your collection of calibration inspection gear with a varied set of used pieces and are okay relying on the pictured details.
- Choose the Stock Equipment C23196-1 Calibration Probe if you need a specific calibration probe model and prefer a new-open-box single item.
