I am pleased to find information on the Little Willie at last. I bought one a few years ago (the 30W 2 x 8" version): it was a bargain secondhand at just under 1000 Dutch guilders. I had just come from the shop over the road, where I had tried the Gibson Goldtone, which was twice the price and half the wattage!
I use it for jazz with a Hofner Jazzica, and it attracts a lot of complimentary comments for its warm, bluesy tone.
