| Description | Box wood crystal models, demonstrating the various crystallised forms of minerals, [19th century]. Annotated in pencil indicating the museum locations of the real mineral. |
| Provenance | The models were originally found intermixed with GSL/OB/4 but are clearly different in origin and of later date. Unlike the earlier models, the name of the mineral is very simply pasted on. There are no facets or edges marked. |
| Access Conditions | Access is by appointment only. Please contact the Archivist for further information. |
