Yep, that's the one. It's amazing what you can find at this place. (Including a good chunk of cpo, I might add. I've picked up more than a few cpo releases there over the years.)
'Here' (the Netherlands) CPO is better ordered online, as shipping from Germany (JPC, it's their home label) is often free. But I'm also lucky enough to 'still'have a couple of record shops around with quite a collection. Not so many of our colleagues here are that well-off. 
BTW Wilms is hardly a name in the Netherlands, he remained largely forgotten until recently.
It's unfortunate - we're losing one of the last independent CD stores in DC next month, and to my knowledge the last one which dealt with classical music much at all. I was there last night - picked up some nice things, but at not-so-nice prices, I'm afraid. And the last time I was in the town wherein I went to college I stopped by the spot where my favorite independent CD store used to be...nothing.
They used to have a remarkably eclectic collection of used CDs for sale there - I purchased some Robert Ashley, some Gavin Bryars, some Smetana...
Ah, well. At least there's my favorite used book and music store. I
always find something there. (Frequently too much something, but that's a subject for another day.
)
