Pick up the baby + basket a few times with one hand to calibrate yourself, then find a spring that feels right at the same force in the store. You could make two small rope or strap loops to hook onto the spring so you can pull it hard enough.
Where in Germany? I was stationed in Heidelberg and Heilbronn and drove all over Bayern fixing comm sites.
I'm in Cologne. A lot cloudier than where you were! What store? A friend suggested the same thing. I was like "yeah, I think there's a specialty spring store just behind the shopping center. I'll just pop over there and see what they have." He said, "no, I just mean the DIY". "Well," I said, "I don't think you've spent much time in one lately if you think there is going to be a large assortment of springs there except for specific replacement applications like garage doors." Maybe not everyone lives like this, but how many of you out there could even go out and buy a 1/4-20 tap in a local store? I mean a real polished hss single tap and not a bs import kit? Brick and mortar is dead, and good riddance, imo. It never was any good.
Google shows seven lettered hits for "Baumarkt Koeln" and "Heimwerkerbedarf Koeln".

Our local hardware store has a decent selection of taps, drill bits etc, though they are pricey. They even had a new starter pinion that fit my 1980's Sears tractor. The better-run stores do quite well despite the big-box competition.
