Trunk pan for a coupe,has the latch piece attached,doesnt look like 28/9 maybe 30/31? Sent from my iPad using The H.A.M.B. mobile app
Is it curved? Might be the filler that goes from the top of the panel under the decklid to the sub frame in a rumble seat "A" coupe or roadster. Has bumpers on it to stop the decklid when it's fully opened. Not a great picture- it's on the right side, top corner. ( not attached, just laying there.) Go to an online "A" catalog ( Mac's) and compare with their picture.
I picked up a nice one last Hershey and yes it is a Model A, trunk pan. The rumble seat pan is different.
