I'm posting this on behalf of a friend as I know there are a few taxidermists on the forum and this is not too common an opportunity.
My mates young Golden Eagle (6 months) that he captive bred himself died following an infection. It has been retained and pending the relevant paperwork arriving he is willing to sell it to a taxidermist.
If anyone is interested please pm me and I will pass on his details. Any discussion regarding costs can be done directly with him.
