ACON Assortment #30 of Pusher Crowns for Pocket Watches in Box

ACON #30 of Assortment of Tap 10 and Tap 6 Pusher style Crowns for Pocket Watches, predominately intended for Modern Mechanical and Quartz Hunting case watches, hence the "pusher", where the center of the crowns operates the hunting case latch - see photos.  Originally containing 20 crowns I count 15 crowns remaining, with 2 in each bottle except 9 which has one and 7 & 8 which have zero. While not stated I'm pretty sure these are base metal crowns and they're even still sold by ACON. I think they're in order so hopefully you can see what has been used and what has not. Images do a pretty good job of representing the item.
