Vintage Sperm Whale solid cast metal paperweights with wood stand, MCM?

Description

Here is a set of four cast-metal sperm whale paperweights with a wood stand.
The wood stand has posts to hold the whales in place.  It has felt on the bottom to protect surfaces.
These appear to be vintage, may be MCM.  There are some scratches on both the whales and the base, but overall in good condition.
Please review photos and description carefully, and ask any questions before bidding as this is being sold "as is, no returns accepted."
