Some useful (I hope!) information:
There were two slightly different types of L59. One type has a larger 'flower' on the headstock, and the other a smaller (2.5cm tall) flower. I have owned both types, and here's how they differed: The first version was, I think, made in the late 80s into the early 90s. The pickups are excellent, loud, even, although unbranded. On my guitar they had no covers. The neck is chunky, with low action. On mine, there was a gap between the maple cap and the mahogony underneath, in the centre area around the pickups. This, and the woods and pickups used, gave the guitar a VERY powerful, fat, lower-middly tone. Darker than the Gibson LP I've tried. EXCELLENT for heavy rock.... not so good for clean sounds, but still adequate. The build quality was generlly excellent though.
I still have my 'second version' L59, with the smaller flower. Made in the early to mid 90s. It has Kent armstrong pickups (Paf Plus I believe), which are lower output than the earlier ones, but sound very even. The guitar construction is different, and has a more solid feel - it really feels like a jap Tokai or Gibson - really.... and there is no gap between the cap and the main body wood. The sound is brighter, but still fat and 100% Les Paul. To get the best out of it for rock music, I upgraded the bridge pickup to a Kent Armstrong 'Rocker' pickup (tacky name... but it's their version of a SD Custom... and is EXCELLENT... higher output than the original Paf Plus, but still very balanced and raunchy).
