Royal Oak, location unknown

This one has been sent by Frank Nethercutt, who asks whether this could be the original sign.

The name the "Royal Oak" is the most popular name for a pub in England, and in Kent alone I have 85 pubs with this name, but as yet cannot identify which one this sign may have come from. However, being a Whitbread pub, that narrows it down somewhat, but may not be a Kent pub.
