Small Individual Silver Teapot Server Caddy English?

Description

This auction is for a small individual Silver Teapot Server Caddy.  I'm pretty crrtain this is Silver and not Silverplate.  The bottom of the teapot is Hallmarked.  I haven't been able to identify the Hallmarks but I suspect it's English.  The Hallmarks are three leaves in a bundle above a rampant lion in a square, a crown above a star in a square, and a rampant lion above another rampant lion in a square.  Below the Hallmarks are the numbers "6 . 1".  If anyone can identify these Hallmarks (see photos) please help me out.  The teapot body material is soft and has 3 small dents.  The teapot body is also engraved with a letter "F" or "J".
