Serial number 06100Z49. I’ve got the top off it and the belt’s gone. There’s a 2005 post about this model number on the forum which brought me here, but the reply link is dead. Most likely candidate seems to be the belt listed for 37545M001Q (BLT8687) but, y’know, I’m a total noob. Broken belt just about has the readable number 2394 stamped on the non-drive side. All advice gratefully received.
