Thank you for your input... I am now worried that I shouldn't use them to shave with incase I break a scale. Are there any tips / tricks to preserve ivory scales, make them less brittle etc, like the tip for soaking horn scales in neatsfoot? I'd feel really bad if I damaged something that a more knowledgeable collector would take better care of.

If you are going to clean them up be really careful if you remove the scales for cleaning as they will be really brittle.
Mappin & Webb are renowned here in the UK for top end jewellery and other products.
At the time these razors were made I would think that their clientele would be the upper class and royalty.
Enjoy your shaves
