How to find a specific make of jeans again?

(I know its not really buy-it-for-life, but it's a 100% cotton, no-stretch jeans which usually last me a couple of years)

Does any one of you know how to find a pair of Levis jeans given the info on the care label? The place where i bought it has closed down, other shops around me are staffed by pupils, and their website returns nothing.

Per the label:

Made in Spain, CIF A 08298606 00501 0126 32x34 267004 0204 08159 LEVI STRAUSS EUROPE MIDDLE EAST & AFRICA 15-23 AVENUE ARNAUD FRAITEUR BRUSSELS, BELGIUM

I believe the part in bold should specify the make (501) and the specific style.

As i don't really care about the brand: Can anyone recommend a decent pair of 100% cotton, no-stretch, straight-leg (but somewhat bulky thighs) jeans which can be worn with (biker) boots?

Thanks a lot for your help!
