Hi Spencer, yes I completely agree.
Love the MGB GT's. Good driving position and all the controls fall to hand just right. I think all those that went out to the US had the black front bumper didn't they? I was a TR6 man myself. Sold my last one some years ago though.
As to engine, frame and chassis numbers, as mentioned by Northernneil again I completely agree. I once had a frame powder coated which filled in the numbers. The powder coating then had to be stripped back so that the numbers could be read as they are a legal requirement (I presume this is the case in the US too?) but more often than not, engine numbers etc get dirty and can be difficult to read, but this doesn't affect the appearance of the car or bike in general. I appreciate that the pipe maker's name, the model and grade of the pipe all affect value (and therefore some unscrupulous sorts might want to amend what is stamped), but they are an aesthetic part of the pipe too (as amply demonstrated by Misterlowercase's pics above). If I had restored a TR or MG, I would want nice decals and badges on it. I think I feel the same way about pipes. I want the pipe to be pleasing to me, I'm not to worried about it's financial value - whether it goes up or down due to any work carried out as this is not where my interest lies.
As it happens, I have seen pipes attacked with tools much more clumsy than Dremels!
During my apprenticeship, we had to be able to engrave copper, stone and aluminium by hand (for correcting errors during plate etching and engravings in general) to far greater tolerances than used in stamping pipes, this work usually being done under a 10X or 15X magnifying glass using a needlepoint picker (or scriber). Although I would be rusty and out of practice, I don't see why cleaning out stamping couldn't be achieved as it is simply as case of following what is already there, albeit wood has a much coarser cross grain than stone litho or soft metal. The tricky bit would be in making the right tool to do the job. Prior to metal type being used in letterpress printing, it was all wood letter.
Sorry to ramble on. Getting misty about the old days. It's all bloody digital now!
