helping Fello TBN'er to figure what model of sickle mower he has

[twlyons1]

I found the model or part number of the rock guard MC2041 and it comes back to a few different models, the pit-man number is 5M 0-337 , there is some green remnants paint with red over it all except the pto pulley and pit-man- very clearly green.
here is his original posting :

I just pick this mower up, the Gentleman I got the mower from thought it was probably a New Idea sickle. I tried doing google search of New Idea, New Holland, and Ford sickle mower pics but have not been able to find any thing that looks close. There are no tags or marking that I can find on this piece. Any help with the brand or model of this cutter would be greatly appreciated. Thank You Desmond Doyle
