This is a New Old Stock(about 40 years old) Mercedes Benz JWIS double row timing chain, its in the original factory box although the box has seen better days the chain is perfect! The EPC lists this part number #A0009977094 for a number of vintage gasoline engines including models in the M108/114/130/180 series of engines.
This part currently lists for about $75 I will sell this one for $55 shipped USPS Priority Mail anywhere in the lower 48. I'll sell the chain for $50 and ship it any way or where at your cost if that works out better for you.
Please contact me via PM if you have any interest or questions, thank you!
