1950 Buick with automatic transmission oil cooler

Hi

I am in the process to go through the DMV in Switzerland (Europe) with my 1950 Buick Sedanet and need an evidence that my automatic transmission (dynaflow) cooler was an original option back in 1950. I have found an ad in ebay: Buick 48 52 Transmission Oil Cooler Dynaflow | eBay but what the administration guy want is something out of a manual or original literature.

Any help/information to get this information is very appreciated!!!

Many, many thanks in advance!

Best Regards,

Bernard

Hope this helps. It shows an oil cooler in the diagram for 1950. Good luck with the DMV.

Group number 4.126 part number 1390697 COOLER, OIL 1948 thru 1952 Dynaflow. It wasn't an option IT WAS FACTORY FITTED ON ALL DYNAFLOWS.

Can you purchase a new transmission oil cooler now or have they long since disappeared.
