1928 Rolls Royce question

Hello-
I am in the theater and using a model of a 1928 Rolls Royce. Where would you find the gas tank to fill up with gas?
Thank you for your help!

Welcome to the forum, what do you mean a model of the Rolls Royce?

It is a life size replica - a shell for a production of The Great Gatsby

The real car the tank filler was behind the rear bumper below the trunk area, but there were different models so there may have other locations.

Thank you!
