Product Details
This is HK part number 241693, German Description 'DRUECKER VFT'.
These came straight out of HK Germany with our recent lot of discontinued HK21/21E/23E parts. I have no idea what this is. We have never had this spare part before. However the shape of the part looks familiar, like I have seen it in an assembly before.
Approximately measurements: Just over 22.5mm in diameter and the nipple on the back is just over 7.5mm.
