Tulip wasn't a German company but a Dutch one. That means if you're going to find your Tulip-branded RAM anywhere, best odds are in NL. There is still a (marginally functional) Tulip users group in the Netherlands, with their own classified ads. The site is in Dutch, but people can read English too. Unfortunately the good news ends there, there are no memory modules for sale and already people looking for the exact ones you need:

(or could it be you already found that site and that is your ad?)
Tbh, I'd suggest looking into Dell 433C memory. Chances are it's exactly the same (and that both laptops come from the same (Taiwanese?) ODM) and that there are a lot more Dell laptops out there than Tulip ones.
