Initial's on the bottom of a TEA CADDY

I’m new, so I want to thank your community for being so gracious as to allowing questions. I have a Tea Caddy-Barbour Silver Company #21 and it has an initial struck on the bottom outside the small company circle stamp of BRL. It seems have been free handed such as a signed piece. Could this be the designer of the piece? Should you choose to reply; thank you, Maudie[/img]
