Well Done David - the revised sitelooks easy to use.
 
Here is something to start things up - fortunate enough to lay my hands on this beauty a couple of weeks ago.  It is a Pattern 1863 Enfield Whitworth in all original unmodified condition with the sole exception of the "S" stamped over the proof mark to denote Sale Out Of Service.  It has its original platinum lined nipple with a flash hole measuring 1/20 inch, rather a large size by match rifle or modern thinking standards but as it was military I suppose it could be understood.
