very different Frosty. SIsco/Soderfors have graceful curves from the feet to waist, and waist to underside of the horn. The feet carry up into the body area more. The original one pictured doesn't have those characteristics, at all.
The one pictured has a very HB style of horn shape, but in a cast anvil..... Not sure what make, but I'd be very surprised if it was indeed SIsco.
