Antique Glass Sealed Mallet Wine Bottle Fox Talbot Dog?

Interesting sealed wine bottle with a dog or foxy wolf figure with TL or JL underneath. There is some possible association with the Lovett family in Shropshire but this cannot be confirmed. The colour is particularly attractive when held up to a strong light showing a rich reddy amber. Height 9.5 inches, width 4.5 inches. Good condition. An old label exists on the back for the Delaforce Collection. English C1780
