Having purchased the special antique wax by Woodoc, conforming closest to your kind advice given so kindly by you all, I have applied two coats and have given the scabbard a good rubbing. Here are some final pics, but I am not satisfied by the quality of the pics, whilst I so wish you could see the deep gloss & highlights that appear on the wood. This does not mean that I am totally chuffed with the choice of wood for the gambar, but there it is now.
Please consider that the scabbard looks better than on the pics!
My wife is waiting in the corridor with a list of work I need to do for her, now that the workshop is available once more - worse luck!
