1879 grade 3 Lifter Engraving

[Austin Smith]

This is my grade 3 Lifter from 1879. A couple of questions I have about this particular gun:

Does this style of engraving have a particular nomenclature? I feel this style of engraving is less common than the Parker style scroll, does that seem to be true? There’s also a few areas that have arrows engraved, like on the top of the action and around the pins behind the hammer seem on picture 2 and 3.

As far as the letter goes, is anyone from Ohio that might know where Leeds used to be? I can’t seem to find any information on a Leeds Ohio currently. Also does anyone know about the Detroit Bench Show? Thank you everyone!
