There really isn't a problem with the IMA guns. You get what you pay for. My first purchase from them was a MKIV. I reasoned that they were some of the last produced and shipped out to india. What I got was a rifle with about 85% bluing, 100+ years of dents in the wood, and about mint internally. For an exersice in restoration I bought an as found condition francotte model. It needs a lot of wood work and will not be a shooter when done. The bore is extremely pitted. The francottes and gehendra rifles were locally made and have had the most neglect. People are reporting that the gehendras are in the best shape of the two. If someone wants a shooter than the untouched unmarked MKII rifles or the MKIV rifles are the way to go. Then there is the cost of shooting a martini. Brass is costly and you need a larger press to handle the larger dies if you full length resize your cases. I only crimp the bullets using a pistol die, but I am only shooting one martini at the moment.
If you want a neat looking wall hanger than try them. If you want more info on those rifles and peoples experiances with them, post on the martini section.
