Right, so we've done two of the three cancellation types: the dotted cancellation and the small circular cancellation. The third one is the large circular cancellation.
These were introduced in 1894 and remained in use during the remaining period of the "Hangend Haar" definitives. Again the post offices and sub post offices used different hour indications: 1, 2 or 6 hours for post offices and 4 or 8 hours for the sub post offices. The cancellations are too large to fit onto the small format definitives so it's hard to find good copies. The two shown here (Rotterdam and Haarlem) are both post office cancellations.
