Also this small button, any advice on how to clean it would be appreciated, I can make out on the reverse T -TR and a couple other letters I cannot make out until its cleaned better.
Hi; The button is a 1 PIECE button. That dates it to older than 1820. The 2 PIECE button came into vogue at that time and basically ended the use of the 1 PIECE button ok. To clean it : Soak it in water for a few days. Then use a wooden toothpick and "GENTLY" "push" the dirt off. This may seem tedious but the results are worth it. Remember that you are only removing the dirt. Dirt becomes solluable when soak in water after a while regardless of how long it has been caked on the object ok. Good Luck. PEACE:RONB
