I bought some old crystals on ebay : http://www.ebay.co.uk/itm/122225114483
Is anyone familiar with this style ? I don't think the quartz is visible in the glass section : I imagine that's just an insulator. I think the quartz is under a brass disc, with a sping to hold the disc down visible through the glass. Does anyone know what the reference marked on them "w'less sets No 7" refers to ?
