Original, used Magneti Marelli dynamo to suit 1900 cars with the dual pulley. Please check the photos against what you have as there were a couple of different types of dynamos that were used over the years.
OE Part Number: DN22B 200 12/1700D
The pulley on this dynamo is cracked so will need replacing or fixing.
We are unaware as to the internal condition of this dynamo so we are selling it under the assumption that it will need reconditioning.
