Ok, so I've got an old RP Black Hawk which is obviously slightly smaller than the more recent IWM sculpts. My issue is several years ago the mech got stepped on and when I got around to getting replacement parts the legs were just fine, but the base with feet molding didn't match up. Apparently they molded differently the ones in the box set with what I purchased as replacements. The easiest thing I think of to fix it so it sits correctly now is either chase down a new set of feet molded into the base, which I don't think is in production any longer. Alternatively, use a set of the new feet, which would be slightly out of scale with the older sculpt. The question I have, for anyone that has both and older and newer model would be; are the legs and foot joints be to dissimilar in size that it would look incredibly goofy or not? Additionally are the sockets inserts incredibly different from the two versions that something other than puddy and filling might be needed to fix the issue? A lack of pictures on IWM site has me throwing the questions out there.
