Some 70 years ago, my elder brother was, for a short time, a Sales rep for Wandess Boring Bars.

So your machine is likely to be of some antiquity This was when he taught me to read a mic! I think that they came in more than one size, possibly three) and were intended to compete with Delapena, who were the generally accepted as the "norm".

Not long before retiring, I was involved in testing an engine which had bee been deliberately bored out to maximum oversize, using a Delapena machine, so they were still in use, until relatively recently.

Improvements in materials, machining processes, and oils have now made them almost obsolete for most newer vehicle engines.

My Volvo Se 40 has just passed 224000 miles & still runs great. It is perfectly Ok. I do not need to give it a rebore. When it gets to that state the rest of the car will be shot. So the engine cannot be that bad. Rather knocks a hole in your comment- as far as my car is concerned anyway!!!
