Lynton in the Minehead Penny Post

The cover below is one of the "missing links", with a "LYNTON" undated circular handstamp on a cover in the Minehead Penny Post going to London in 1837.  It has been known that Lynton was in the Minehead Penny Post and covers from Lynton (or Lynmouth) in the Minehead Penny Post have been found, but this is the first cover recorded that has an identifiable Lynton handstamp on it.

I'm looking for covers from the 1832-1835 period when the "LYNTON" udc is known in use, to see if these are also in the Minehead Penny Post.  Unfortunately the only one I have found so far, from June 1835, does not have a recognisable UDC, but does have a circular "smudge of approximately the right size. 

If you have an example of the Lynton udc on cover, then please do send me a scan.
