I found some plaques from the "attic" of Club Privé du Kursaal Ostende.

These "type B3" plaques are rare but the 5k plaques are super rare.

I only have 1 double, so far only 3 are known.

Shoot me an offer or propose a trade for MOP or Belgium I do not have in collection (see CG, my collection).

Enjoy, CG315301 as of tomorrow.
