Above is the updated price guide, McQueen 1133b still in demand, along with cal15's, manual wind 73633 less so, although blue still attracting more interest than grey. Same can be said for 1133G v B. Rare models as elusive as ever, especially so in mint form and to that end a small note on authenticity and dial conditions.
