Introduction

Thank you for your willingness to share documentation from your pre-existing examination of a movement.

This project focuses on non-numbered, 18-size, private label Century-grade Seth Thomas Models 10–13.

Contributors are not expected to interpret findings. Clear photographs and accurate transcription of markings are sufficient. All evaluation and classification will be performed within the research framework.
