litespeed frames after the lynskey family sold the business have a reputation for not being quite so good. the manufacture went from in the USA as a family business to being outsourced. there are lots of threads about their warranty issues on other fora, eg MTBR
however this caused such a backlash that they seem to have improved on this, so you may wish to see if you can get the original owner to contact them on your behalf, as originally they came with a lifetime warranty
