Hi all, Just Wondering if anybody could tell me the correct crown/ dimensions for a Polerouter 22017-4 ( and 3). From my understanding, some models of the Polarouter may have come with an unsigned crown within the second execution, but were these crowns carried on to the early Polerouters as well? Quite a bit on the forum already, but I haven't managed to find the correct dimensions for the correct crown. Thanks!!
