I availed myself of this service the other week. They didn't really have that many on offer, their entire collection fit in a couple of cardboard boxes. Fortunately, they had one of the eight I was looking for. I also had a backup list of three houses that are showing their age sufficiently to warrant replacement, and they also had one of those.
Interestingly, the new #18 I received (well, it is actually from 2002) does not look exactly like my over 50 years old Rynbende one. The latter still contains 35 mm of (by now "zeer oude") jenever, by the way.
