Vintage detachable starched wing collar, style "Scott", with a registered trade mark that might be the Blackpool Tower.  Presumably named after Captain Scott, who died in 1912.
Studs not included.

SizeCollar size 15 (to fit shirt size 14.5)
Depth 1.5 inches.

Condition: Vintage collar, around a century old, in good clean condition, but with a crease in one wing tip (this should obviously come out when the collar is relaundered and restarched).
