Gruen Factory stems (pair) for caliber 270, 271 - new in envelope

Pair of GRUEN factory stems for calibers 270, 271 and perhaps others, new in envelope. Originally came as part of factory assortment #54. They look to be in fine shape but could use a cleaning. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. If you need a part for a Swiss watch I likely have it so feel free to inquire. Images do a pretty good job of representing the item.
