Hoping to track this down as a specimen or any info on this style of bottom-weighted script! I imagine it would be from an english foundry 1870s-80s

These were probably just local print. It would be better to ask locally about history, but I'm not sure about making it into a font per se. The most similar I could find would be: Seashore Pro

I came across that as well using whatthefont, thanks! @MissNobody

It could be Lakeside Script (or a knock-off).

Brilliant, Grazie, @Riccardo Sartori!

It is likely a custom engraving of hand lettering in the Zaner Script style.

 

There was an 1880s typeface based on this style called Spinner Script, but your sample is not a match.

Seashore is your best option for replicating the look. P22 Zaner would be another option.
