Sanctus Seraphin violin: single piece backside

Sanctus Seraphin violin: single piece backside. Body is 35.8 cm. long. Shoulder is 18.5 cm. The neck is 13.7 cm.
Sanctus Seraphin worked under guidance of Nicolo Amati before 1692, his instruments' versatility of modeling a remarkably characteristic feature combines Amati, Stainer and even Magginiinan original manner. Varnish mostly a golden-brown, sometimes a orange-red, occasionally a dark-red. Generally of brilliant appearance, often splendidly transparent and soft, but also at times rather hard and dry with its usual accompaniment of crackling. Nearly always plentifully applied. Tonal quality resonant and very responsive, not of extraordinary brilliancy but of good carrying power, richly mellow, and in fact all the attributes that soloists are continually hankering after.
