My perspective is 2015.  With Original Krag rifles getting scarcer every day, it seems a shame that any of them were used for experimentation.  While a pump action Krag may be a novel idea, I don't see any practicality in this design.  Most pump and lever guns have the advantage of reloading the chamber without taking the gun from your shoulder.  That doesn't seem to be possible with this design.  It has no collector value, it's not very attractive and, while the idea is novel, it's just not practical and not very attractive.
