Vintage Scovill 10k Gold & Sterling Service Award retailer Company Tie Tacs - Enamel

retailer I have tested the unmarked one and it held up for 10k and 14k but will only figure it in the price for 10k.

The diamond one is marked 10k LGB and the silver one is marked Sterling.

Size:
Silver: 13.67mm x 11.65mm, 1.7grams
Gold: 13.5 x 11.61mm, 1.6 grams
Gold with diamond :14mm x 11.75mm, 1.6 grams

These come from the original recipient with the L G Balfour Co Box.
