Tom, these are v. good photos of '28 '29 'shells, both repro & originals.
The last ones of the crank hole area is maybe not 100% correct for all Model A's.
Although US production in '29 used the 'shell with the 'bell'' embossing [ to strengthen crankhole probably], the '28 style [ not bell embossed] was also used with '29 Twolamp headlamps that had the larger conduit hole. I have seen many ''29's, all Canadian export cars,& nearly all did not have this feature; the one I do recall had been put on a '28 54A by mistake. My late '29 Canadian has the '28 style crankhole.Until recently [ Ive owned my car for 43yrs] I did not know there was a difference in this between the US '28 '29's.
