I had a customer bring me 2 older rugs. One is an arctic fox and the other is an arctic wolf that belonged to his father while he was patroling the Inuits in Canada. The customer doesnt have much more info other than that they were mounted and rugged 40+ years ago. There is no padding only a fabric backing and felt border. They are quite musty smelling and the fabric stinks and is stained as if water damaged. I feel that rerugging would be the answer to the fabric issue but could I wash the furs? I am not sure of the tanning method that was used so I am a little worried about soaking them down and washing . He also wants all the options including remounting the heads and having them rerugged w/ padding. do you feel that I could rehydrate and remount them? I understand that some of the info that I have is vague, but it is all that I have to go by.
