KK Assortment of Vintage Genuine Gruen Stems in box

KK Assortment of Vintage Genuine Gruen Stems in original black box, preowned. These are for very old Gruen movements, not more modern ones, so many of these are very tough to find. Originally containing 36 pieces I count 30 remaining with all containing at least 2. Please do not be deceived by the outer box as it does not contain Bulova stems - my theory is someone mixed box covers many years ago. Hopefully you can assess what is left, and what calibers they are for, from the images, if not let me know. Images do a suitable job of representing the item.
