VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1912-1928 28 AB National touring windshield frame

can anyone please advise regarding my '28 ab national touring restoration project ....
Both top and bottom windshield frames are corroded which i'm told is quite usual .
.... The upper frame is just about salvageable but the bottom frame is completely rusted
out beyond any repair .
Because (depending on availability and cost ) i'll need to obtain a similar replacement bottom frame and with very little chance of finding one here in the UK , i'd like to know is the bottom windshield frame unique to just the 1928 touring ?....
or were they also fitted into any other models or years ? ....if so, this would give me a greater chance
at finding the parts to complete my windshield assembly ...thanks
