How far did Sevens used to go in the old days between rebores, please?
The engine block on my Ruby is likely to be original (Feb '37) from the M number stamped on it. Given it is currently sleeved and bored to -20 thou, would this suggest that the total mileage the car has travelled is about 5 rebores x 20K = 100K miles, or maybe a bit more? The speedo currently reads 22K - perhaps this is suggesting that the total is about 120K? (That is not a lot in 81 years, though.)

My three owner 1929 fabric saloon was fitted with the original light shaft coil engine until around 1971 and covered 78,000 miles in 51 years.
Unfortunately although the original owner kept some records there is no mention of rebore, but this could possibly have happened at around 60,000 miles.
For some unknown reason the original engine was removed at this time and replaced by an earlier magneto engine at 78,000 miles.
The original engine had been carefully stored and was still with the car when I bought it from the second owner in 2015. When checked it was surprisingly in very good condition so the bores were honed and the original? pistons and rings refitted- unfortunately I didn't note the bore size, but I believe the block was still the original.
The second owner only drove the car on car club events over his 40 odd years of ownership so the whole car would have only done some 80.000 miles in its 89 years.
