[Ron Wood]

Gerben,

As you may already know, the Dutch wood base magazines are found in three versions. The early magazines were fabricated with a spring catch in the wood base so that it could be removed for cleaning the magazine interior. A good idea for tropical climates but in practice this spring failed frequently. So many of the early magazines will be of the second version, having a pin added to secure the wood base thereby rendering it non-removable without a punch. The last version has the standard pinned base without a spring catch.

The early spring catch magazines in good condition are quite scarce and a bit costly. So if your magazines are of this type, it might be a good idea to use replacement magazines for shooting (probably a bit more reliable too).
