I have never seen this system before but I can give you a couple of pointers
to similar approaches:

1 C  : a) 13-15 Balanced.
       b) 11-15, 3 suiter short in D.
       c) 16+ any distribution (except 16-18 balanced).

a) The Swedish Carrot Club which uses 1C for 9-12 balanced OR 17+ any 
   distribution. Some of the world-championship books contain information about
   this system. Maybe one of the Swedes on the net can give you a pointer to a
   more detailed description.
b) The club system devised by Alex Fransz of Indonesia. He has published a book
   about it called "Medium Club Relay". It uses a 1C opener for (a) 16+ any
   distribution, (b) 11-15 with clubs and (c) 8-11, weak two suiter including
   clubs. The book describes the followups to 1C in great detail.

2 D  : 55 not both minors, 7-11.

This is the Polish 2 D opener used by lots of Polish pairs in international 
competition. The only description with example hands etc that I have ever seen
was in Polish. Since you're in Amsterdam, you might want to contact Roald Ramer
(Originally from Poland but living in A'dam since many years) for more details
about this opener.

(And if you ever find a book/article about the Polish club in English, let me 
know. I have been looking for that for years).

2 NT : 55 minors, 7-11.

For a followup on 2NT try Garozzo's book on Volmac Precision. In fact, he uses
3C for a weak hand with both minors but that doesn't matter for the relays after
2NT (3C).

BTW: Are you allowed to use this system in the NBB? Both the 1C (conventional
club in a not well known system) and 2D (weak hand with both suits unknown)
opener look like red conventions to me. 

Henk.
