Taunton Penny Post - post-1828 but too early for receiving house handstamps

Here are a couple of examples of entires in the Taunton Penny Post that were too early for the post-1828 receiving house handstamps.  The first is from Crowcombe from March 1828, which a little later had the unboxed "No.3" receiving house handstamp.

The next is from Williton from February 1828, that a little later had the unboxed "No.6" handstamp.
