Thanks chaps

Sorry Mad Doc - I must indeed have missed your question over at Steve Dean's...
There are a measly six sheathed sword and buckler combos in the box, and 40 figures. So you're never going to be able to convert more than a handful into sword and bucklermen.
Yes, many of the left hand bow arms are in positions which lend themselves to adaptation for a buckler, so that's easy enough.
The difficult thing is the sword hand. There being no bare swords provided (so you have to shave down one of the many sheathed swords included) and only two or three 'open' right hands in poses that lend themselves. That said, I'm sure that with more major surgery, some of the polearm hands could be drilled and opened to take a sword, but I haven't tried that yet.
But yes, if you were determined, you could certainly get six sword and bucklermen out of every box of 40.
Let's hope that in the second boxed plastic set (pikes, crossbows and handguns supposedly), they also include a few more loose weapons and shields.
