Ah, thanks for the tip, hopefully will be able to try it out in the next few days. With the feet, I found a video from Echotransformer showing the shapeways prototypes - he angles Swindle's feet slightly down to insert them into the foot, but I think they straighten out again when it clips in. Might be worth having a watch through to make sure the supplied instructions actually match up with what you're supposed to be doing.

I can understand the omission of a weapon, especially when it was a shapeways project but when it went to mass production, I wouldn't have expected the cost of a new gun to be significant. I tried a Franken-gun for a while but ended up settling on just using Brawl and Swindle's guns, with the rest mounted on the back cannon. Now that he has decent hands I might just ditch all his weapons.
