Unknown Military Button...

[nickmann101]

Hello,

I wondered if you might be able to identify a button I found, it was in with a few railway buttons but I've been told it is doubtful it's rail related.

I've attached a couple of photos, but I'll also describe.

It features what I think might be a QC Victorian crown. Underneath it has three symbols all lined up, Tudor Rose, bull coming out the top of another crown, portcullis.

It is made by Firmin and Sons London.

Any help would be great.

Unfortunately it has lost it's eyelet to the back, but still a nice looking button.

Any help would be great

Nick
