Antique Low Hinged Port Bit (by Metalab)Here's a very effective bit from Metalab with a sweet iron curved mouthpiece and flush copper barrel hinged port. The 7 1 2 cheeks slide for a gag effect, and are beautifully antiqued with stainless steel dots. The mouthpiece is attached at bottom of the tubing, creating a higher purchase and more action at the poll. A Metalab Level 2 (moderate) bit. Size: 5 1 8"
