New Haven Calendar Clock? Movement Time Only 8 Day

This is a New Haven, time only clock movement. I believe that it has calendar complications. There is a star gear on the rear and an extra linkage on the front. The movement is on the clean side with an intact spring and power transfers through the gear train. View the pictures and ask questions prior to purchase. This movement was received loose and is being sold as found. There are no maintenance records, and I haven’t seen the movement.
