Nice book! Congrats! I've been wanting to order a Kalkamel for too many years now, so I should give in!.
The musette is a fantastic bag for an everyday carry, and worth finding an original on the French military websites. If one is a photographer, Billingham do a fantastic insert that fits perfectly into it. Great for travel, as the bag looks so old, it's not a target for thieves.
Padded Inserts - Olive / Hadley Small / Small Pro .
Even add one of the clasp buttons behind the bag loop in between the pockets to to connect the insert to the body And well, the monopod loop on the bag, is perfect. And well... comes with a great back story of being a WWII ammo bag.
Also a great work bag!
P.S: I feel so bad for the people that buy those Nine Gates on Ebay from Lulu for crazy money...
