RARE Antique Arthur John Seward Copper Riveted Arts & Crafts Match Box Holder

Description

Rare piece of Art & Crafts hammered copper made by Arthur John Seward.
This piece appears to be a match box holder but has an unusual piece in the middle that I cannot quite make out it's purpose for.....
The piece has a hammered finish and riveted joints. It has not been cleaned.It is riveted to a base that measures 3.5" x 2.5" and it is 3.5" tall.
Wonderful arts & crafts/mission style and look!
His pieces do not come up too often! Makers mark on the base.
From the WEB:
Arthur John Seward
, 169, Pershore Road, Edgbaston, Birmingham.  His products are handmade of copper or brass with a hammered finish & riveted joints. Most have been silver plated but some are left copper. Items include candlesticks, bowls, ashtrays, matchholders & what appear to be vase holders. The designs hark back to around 1890-1900 being very Arts & Crafts in style.
The makers mark - 'HS' may stand for 'Homespun', a name used on a range of artifacts that he made.  Arthur Seward had been a photographer's manager before starting his own business.  He retired and left Birmingham in 1921.
