Thank you for viewing! This is a HOBBY JAPAN winding thumb rest (for Leica M10 series). It is compatible with the entire M10 series, excluding the M10-D. I am selling it because I no longer have the M10 body. Currently, the distribution volume is very low, making it a "rare part" that is difficult to obtain. For those who use the M10 series, this item greatly improves operability and appearance. ⸻ 【Condition】 • Appearance: Some of the paint on the parts that interfere during installation and operation has peeled off, revealing the metal underneath (please check the photos). • Operation: Good, with no problems. Movement is smooth. ⸻ 【Included Items】 • All original accessories are included. ⸻ This is a rare item and a highly practical part that makes the M10 series more comfortable to use. After your order, I will carefully package it and ship it promptly. Please consider it. - Product Name: Thumb Rest Lever for M10 - Accessories: Instruction manual, parts - Color: Black - Design Features: Ergonomic shape - Material: Metal Thank you for viewing!
