This badge was worn by officers of both the 1st and 2nd Battalions of the Sheffield Volunteer Defence Corps from their inception through to redesignation as volunteer battalions of the York and Lancaster Regiment. 

This was worn as a collar badge by Officers. It is made of bronze metal and has a laurel wreath surrounding a shield with the arms of Sheffield (the sheaf of arrows and 3 wheat sheaves) surmounted by an Imperial Crown.  

Beneath the wreath is a scroll with the letters SVDC (Sheffield Volunteer Defence Corps).  The badge is on loops and has the makers mark JR Gaunt London stamped into the rear of the badge.

It is difficult to find photographic evidence of the badge being worn but a fundraising postcard exists for the 18th West Riding (Sheffield) Volunteers. This Bn became the 2nd Bn Sheffield Volunteer Defence Corps (SVDC). 

This post card shows the battalion commander, Maj HA Cole, wearing this collar badge.
