Better than average!
Bolster most likely from " white brass" : >49% zinc. Identifying it is simple, but not practical on finished and engraved parts : get a good sample of fine filings and add just a bit of strong vinegar. Zinc will start emitting bubbles. Unfortunately, they are virtually never dated; my guess second half of the 19th- beginning of 20th century. |
