I bought these direct from Germany, costing about £25 ea + c.£10 postage, so about £60 new.
The Oval mirrors are a current Gazzini design which can be viewed on their website.
Fittings provided allowing attachment to bars about 20-30mm. width of attachments looks to be 12mm
They look fabulous - quite stylish
