They are exactly the same. The equivalent of the 201-2 produced at the Kilbowie Factory in Scotland was given model number 201K2. For some reason the potted motor wasn't as common as the belt motor version, and I have never found an explanation for it. There are a few of them though. Unless it is the bit more angular and later aluminum version, I think the spool plate is missing. The spool plate easily comes off, it's just pressed on but usually it stays in place.
