Swiss collets for trade

[G-rhymesD]

I have 2 Swiss collets for trade both are for slotting Saws. The collet thread size is 6.8 mm and I have some misc drawbar that comes with them. The boss size on both are .392 so probably a metric sized saw. I’m not sure if these are home made. Let me know if interested, be happy to answer any questions.

The collets screw into the drawbar by the way...
