This is a cylinder head timing adjuster/ tensioner and gear off a 1969 Alfa Romeo Giulia GT 1300 Junior.  The gear is currently stuck and only wiggles a few degrees.  Good teeth though.  Overall this will be a good one to work with.  You cannot beat the original old parts. Get this for now or down the road.  Overseas shipping no problem.  Shipping is gladly combined on multiple purchases.
