Wharfedale vintage bookshelf speakers

i've found a pair of small wharfedales at a garage sale. they look great. probably 20-30W at 4-6 ohms. i can't identify the model, other than the wharfedale logo, there's no sign saying anything. they're made in england, 2-way and that's about it. anybody can direct me to a list with wharfedale speakers from the 70's?
