old school and rare (almost impossible to find any info on google) P.S. OLT Co MKV Duck Call.

I tracked down some info from an 'expert' that tells me this is from the 1960's and made of Alivera Gondola wood.
overall length of 6".

Best I can tell, this is from their "magnum" and/or "magnumtone" line of calls.  literally the only thing I could find online was an old auction selling one of these and had that info in the description.  sell price was $275.

the outer layer of the call looks to be cracking (tried to get a good pic) but it doesnt feel like its actually trying to peel or come apart.  hard to explain, its like it looks a lot worse than what it is?  just trying to be honest.

$100 shipped CONUS with tracking
