BEAR LITHIA WATER NEAR ELKTON, VA Early, Blob Top Variant??

This bottle was dug in the 1980s at the old Myrtle Ave dump in Jacksonville, Fla by the late Edgar Masters, one of Jax' most successful diggers. He then sold/traded the bottle to his cousin, Warren Masters, a long time collector. I was fortunate enough to acquire this bottle from the estate of Warren and I've had it for about 10 years now. The newspaper ad is from 1892. I believe this is an early variant because of the "blob" type top. If this is incorrect, please advise.
