I built the kit several years ago. Detail is lacking in some areas, and there are some inaccuracies. I replaced the two recuperators with brass tubing, scratchbuilt the main gun shield from .010" styrene (kit shield is way too thick), rebuilt and folded over the automatic loader, cut off the fuser covers and drilled out the fuser hole locations, added a new handle to the breech and to the fuser box, cut off the molded chains and added real ones, and then added it all to the pretty much rebuilt 8-wheel transport carriage. Out of the box, the 88 is a good kit, full of detail. Because it's as old as it is, it really needs some TLC to get it where it needs to be. If I can figure out how to do it, I'll try to get some pics of my 88 on here.
The Schiffer book on the 88 is the best reference I've found.
