Not sure I can point out any particular source but what you can do sometimes is find something close and things like cattle horns can be made and added on some of them. some wire with some glue added to make the thicker at the bottom of the horns, smooth them and some paint could look pretty good
I am working on making my own round hay bails. A friend of mine wants to just purchase them and for the most part will probably end up looking like a plastic item. I am using the little moisture absorbent canisters that come with some of my medicines and will wrap twine round and round on the flat sides and tall grass material around the edges. Wrapped with some bailing material I think my bails will look real when I get done and better than the plastic ones. Not trying to out do him but just trying to out do him. And I think I can do it cheaper than the commercial ones.
I am working on an Indiana State University “Sycamore Sam” which is basically a short eared Wyote Cyote from the cartoons. I have ground down the ears of the Wyote Cyote and just have to put him in a Blue and White outfit with a tail. This is going to be part of a Passenger end car whith all the chear leaders standing on the Platform of the University private Car
