Thanks Pitchfork. The GBD is very thick walled 5/16th inch so its capacity is about the same as a group 3. It is super light and has a great bit. I love to take it on short walks. It will hold about 1 1/2 coins of Escudo. I cant wait to see what Bradley posts. Probably something along the lines of a Dunhill 6103 or similar. :lol:
