No disrespect to any of the posters but all this talk about a bleached skull, cleaned boiled out and not on a plaque being considered not finished is B////cks. Certificates for raw skins that are dipped and dried is one thing, yes they are raw skins and unfinished, but cleaned skulls. Strikes me this is just another way of ripping people off big time.
I use K.G. Logistics in Kent, always have done, never had a problem.
I would add that over the past few years I have heard and seen more and more people having difficulty shipping their trophies back. Back in the early 1990's we had some of these delightful taxidermy companies in Africa spraying peoples raw skin trophies with Formaldehyde. This rendered them useless to mount as they go like sheet steel and will not rehydrate, I know this for a fact.
Either way most taxidermists in Africa do not like loosing the work, and getting anything shipped back can be a real issue at times.
