Yeah, I've seen the Laser series before, but never heard them. I seem to remember the verdict being positive in terms of sound-quality (They had one notorious speaker-series that gave them a bad rep for some time, but it was an economy-priced line if I remember correctly... They actually made some really-nice speakers throughout the '80's that fell under the radar for various reasons).
I picked up a pair of Laser100's a few years ago for 20 bucks at an antique mall and couldnt find much on them either. HiFidatabase has a few of the lasers out there but not the 130's.
Manufactured from 79-83 and apparently their budget line... But still Wharfedales and going by mine and the way yours look, they hold up very well.
I've only used them as "B" speakers and they sound really good... not the best of my bunch but no complaints for sure.
Heres the link to mine... there are also 60's, 80's, 120's and 90's out there and a couple have user info/reviews
