This is an original Model A Ford Rear Gas Tank filler Screen.  It is the threaded style Filler Screen.  I believe it was used from the start of Production to 1930 and then again in Late 1931 to the End of Production.  The Screen is in good condition.  This can be seen in the pics.  I lightly bead blasted the Screen.  The (12) pictures show the condition of the Screen very well.  If you have any questions or need more pics just send me an email.  I always leave feedback after feedback has been left for me.  Insurance is the responsibility of the buyer.
