The firm manufactured scleroscopes for testing hardness of metals. The original models, made for decades, have a glass tube. They were replaced by the models C and D which are all-metal with a dial, and finally an early electronic version. Apparently Instron Corp. owns the rights to Shore products, but we have been unable to learn details.

- Thank you to member Leonard Pouge for bring the Shore scleroscope to our attention.
- Thank you to Tal Harris of Teledyne-Allvac for contributing a file folder of Shore publications for scanning. His firm acquired a pre-1925 Model C-1 scleroscope with surplus rolling mill equipment from Firth-Sterling Steel in 1968. It remained in use until 1973 when replaced by a new Model C-2. Firth-Sterling was an early user of the Shore scleroscope, as cited in Cassier's Magazine in Sep. 1908, page 399 (Vol. 34, No. 5).
