No that is not correct. There are FORD APPROVED accessories and non-Ford approved accessories. The Ford Dealer sold both. Additionally, all of the scores of other accessories sold by Western Auto, Montgomery Ward, Sears Roebuck, Auto Shops, Garages, Gas Stations, etc., etc. are ALL acceptable for application and use on the Ford Model A.
The 'crunch' comes when one is interested in building a car expressly for Fine Point Blue Ribbon judging at a MARC / MAFCA judging event. But there too non-Ford approved accessories are acceptable. The number and type is limited, so a thorough reading of the Judging Standards is necessary to sort out which, how many, and what type accessories are acceptable. The Standards are quite specific about what is allowed and what is not. But even so, there is still room for some latitude of one being able to use a number of various kinds of accessories. For example, the Lock that fits over the Lug Nut is acceptable for Fine Point judging, I believe.
