Serial Number 18102761 was reported as inaccurate.

Note: This example is a bridge plate model, not a 3/4
plate model. It appears, at least loosely, based
on the pictured examples, that seven-digit serial
numbers (earlier examples) are 3/4 plate and
eight-digit serial numbers (later examples) are
bridge plate models
Curator Response: Thanks for the report. The database has been updated accordingly.
