Hullo everybody
I tend to support Rick's suggestion. I'd even go so far as to suggest that the inserted 'eyes' were 'sparklers'. Has anyone considered that this figure is a representation of a female?
There are those who believe that buffalo horn tends to turn 'brownish'/caramel-coloured with age (after about 100 yrs). This colour tends to turn 'whitish'/'milky' with further aging.
Best,
