muskrat blades??

[joerc2002]

How many different blades did case put in its muskrat blades?
I have several muskrats some with the serreateed blade
But I have a pre 64 muskrat and neither blade is a muskrat blade ..
For years I was sure it was a repair job because both blades say casexx and not muskrat.
But showed it ot a collector and he says pins have never been out far as he can tell???
I say to him NO I am pretty sure its a repair job,
He says ok, then smart guy.. Price it to me ..
I suddenly become not so sure and "very afraid of him"..
so i put it in my little pocket and walked away from an embaressing moment..
So is this guy yanking my chain???
Thoughts Please....
