Can someone help identify this sword

[Paz]

Hi all. 

 

This is not my sword, but it belongs to a freind, whom I've offered to get some sword ID for. He's got a nihonto which the previous owner did a shody polish job and ruined parts of the blade. The sword is difficult to really identify,  but im hoping the photos help. The terrible polish job also ruined some of the hamon. 

 

Hes been told by some people that it could be early muromachi. Or maybe even showa. 

 

Any help is appreciated 

 

Thanks

Definitely not Showa. 'One-hand' nakago and longish blade suggests Muromachi.  The near non-existent hamachi also suggests old with numerous polishes.  From the photos the blade is redeemable, but whether the cost of a polish is worth it needs close in-hand inspection.
