silver pencil 1917. to sapper from General

found this pencil while digging on an allotment in Sheffield. Still contains lead end turns to extend lead.

personal message on one side says SAPPER FLEMING FROM GENL BAITHWAITE. AUG. 1917

otherside says E.BAKER&SONS PAT.798510 RoNo566825 STERLING SILVER

the end that you turn has another number RoNo565713

there is one lead in the chamber and one spare lead inside

on doing basic tinternet research google keeps recommending spelling fleming with 2 ‘ms’ and suggests that Baithwaite should be BRaithwaite- could the name spellings on the pencil be wrong?
why would a general give a silver pencil as a gift? was this common?

can anyone recommend how to sell this item value etc

dont want to sell it to pub land lord who offered £50 but skint x x x
cheers miss rascal
