Ok

I also had a thought: when i was going to try and do this for the mk1 club shop i was going to get a price for club members etc.
If you are short of numbers to get the first batch made up, then mabe contact Richrad Brett (club shop) to see if this would still be viable. this way it will be a benefit to club members. It may be possible for the club to pre-purchase a number but not get them made up till the orders come it to get the customers colour chioce. (i guess the company just will want 'x' amt to start a new run.
I guess once they have made the mould then it would be possible to get futher orders made up as required one by one.
