Vintage 1960s Kolpin Black Soft Gun Case Sleeve Stock No. 302 New Old Stock.

Not sure how long or what gun it’s fit. It’s sealed in package. I’m sure if you know guns you’ll also know what the case is for. It looks black there is a litt opening at the top that I was able to get my finger in the case is almost like cotton soft with what looks to be leather? Trim. So please look at all pictures which are part of the description and information
