Myford Ltd website also has what appears to be a full record of serial numbers. To be a Tri leva it has to be an ML7 ( beware that the Tri leva bits may have been added at a later date) you might be able to read the number again with a more enlightened view to try and make it fit into the ranges published there
i can't find any site that has serial numbers beginning with KSL …. not to worry i have been told 63 to 66 so that's good enough …
