Welcome to the forum! I'm sure many others will agree that it's becoming hard to find the more specialist boat items in most local model shops. I don't necessarily agree with the trend, but it's now almost essential to buy many bits via the internet if we're to ever get any building done. I've used several suppliers in the past - Cornwall Model Boats, Westbourne Model Centre, Jotika, etc. etc. I tend not to favour any one supplier, but to buy from whoever has what I need in stock and at a fair price. Have fun!
