Very Rare Duv Coy Dove Call with box & instructions - excellent condition

This "Duv Coy" dove call is a very rare item to come across and as much as I've tried I was unable to find any information online about them other than for one old listing that offered a decent looking call in a beat up scribbled on box without an instruction sheet.  I did contact a call collector from an USA call collector association and was advised he had never seen one of these in such excellent condition.

This call, box and instruction sheet are a rarity and something that will unlikely come along again for a long time if ever and probably not in this condition.   The price is firm and will be shipped in an extra small Canada Post flat rate box for $25.00.  Cash or EMT only.
