Someone sold an 870 Wingmaster, ca 1955, for 189$. Madness?

Came across a used 870 wingmaster for sale online. The ad stated it had been sold already, but I messaged the seller and asked how much he sold it for. He replied he sold it for the liste price of 189$ (2000 Norwegian kroner). He claimed it was made around 1955. Condition was aparently pretty good. My immediate thought is that the price was way low, but I could be wrong. Just recently got interested in 870s. Any thought?
