Thank you Marcus, but we better not express values under discussion terms; only (non posted) considerations on prices accidently shown in Web images .

You are not assuming that my powder tester is as new as 1920
I would be most surprised that you door handles are of horn; may i call it insolit ?!
But if you only refer to its shape and apparent method i don't need to remind you that such design may be centuries old .
