Need help IDing this button

[Merf]

I have never seen this backmark before--[Crown] It measures 1 1/8 in across.

Not seen this backmark either, but looks like a crude Victorian Crown & I would say it falls into the Hunts (Sports) button catergory of late 19th C. Very nice looking one at that

That is a great button!

Its a Livery button. These men had very elaborate uniforms. The crown looks Tudor.
