It is on a touring sedan. But knowing these were assembly line cars i would assume a convertible coupe could have been produced at any point in the run.

That is what i thought. But upon further research i have found other 120 cars with 5 numbers after 999. which makes sense with a production run over 40,000. as an example note image

I am working on a 1936 120 convertible coupe. No tag. I have an old Alabama title for the car. the vin number states 99931762. Understanding the number of 120s produced in 36 i would assume this to be accurate. 999-31762. However I have never seen a plate with more than 4 digits after 999. Would that number be correct on the original plate. Or am I missing something. Any help would be appreciated
