Re: "PUZZLING TR3 QUESTION"? Please Help:

The early TR3As - like my black one attached - had grooved letters. Later TR3As - like the green one I finished in 2006 - and some TR3Bs had smooth letters. I say some TR3Bs, because, as the story goes, the factory ran out of letters and so some TR3Bs came to North America without any lettering across the apron.
I have my own theory on this...and it is ONLY a theory based on some original cars. I suspect that the change to the smooth letters did come fairly late in TR3A production. My theory is that it may have coincided with a new set of tools for stamping the front end.
My rationale here is that much of the body had been retooled at TS60001, as the original dies were about worn out. But the wide-mouth apron was much newer and was NOT retooled at that time. Some folks have noted that very late original aprons are indeed of a slightly different profile from the top of the grille back to the leading edge of the bonnet; as I recall, it's a bit flatter just above the grille opening. Meanwhile, the 3A would've been the only model using the old ribbed letters, while many thousands of Heralds had already been built with the newer smooth letters front and rear. So it only would've made sense to "rationalize" those across all the models being built.
Certainly the new apron could've been phased in in such a way that occasional older aprons (and thus their ribbed letters) still made their way onto new cars on the assembly line, and it could also have been true even with the 3B. Remember, the bottom pertty much fell out on 3A sales in 1960-61. So when the US dealers and distributors came up with the idea of continuing the line a bit longer at a price lower than the new TR4, Triumph -- with enough bits lying about to easily build a few thousand more -- were only too happy to oblige.
As for the complete absence of letters on "original" TR3As or TR3Bs, I'm yet to be convinced, but it's certainly possible. As Randall pointed out, later replacement wide-mouth aprons appear to have been made with no holes at all. That was also the case for many, many years with the Tasker Metal Products replacement apron, sold for so long by JC Whitney and others.
Again, all conjecture; use this information at your own risk. /bcforum/images/%%GRAEMLIN_URL%%/wink.gif
