Microscope
510 (Unassigned
maker; linen prover; mid-19th century)
Microscope 510 is a
linen prover, probably dated to the mid-19th century. This
instrument would be used for counting threads in fabrics (the number of
threads per unit of length provides evidence of a higher quality of cloth).
The instrument is not signed but should have a French origin. This instrument
was described in catalogues of G Fontaine and Buron
as “compte-fils de forme
ronde” (Figure 1).
