The catalog listings we have span 1963 to 1967, but we don't have a specific model tied to this number in our records. If you're trying to match this up to a particular bike, give us a call and we'll work through it with you before you order.
Coils like this one are a common failure point on older ignition systems, so if you're chasing an intermittent spark or a no-start, it's worth checking early. We don't have further material or dimensional specs on file for this part beyond what's listed here.
