Half rattler grind Colley & Co.

From one of Neil Miller's posts I learned the Sheffield cutlers referred to this grind as a half rattler grind. I have also seen this grind with blade stamps that say double concave. This blade is 7/8 with the blade face stamped 'Manufactured for W.W. Messer Boston'. The original finish was a crocus (mirror) finish. The original dyed horn scales, flat with beveled edges and a lead wedge were replaced with copies in faux turtle (Tortuga East polyester). The originals varied in thickness from .120 to .110. These are .110. I haven't yet figured out how to inlay an escutcheon into this soft material yet.
A little history on W. W. Messer & Co. Boston. From 'A Strangers Guide in the City of Boston' published in 1849. W.W. Messer opened his establishment in 1837 for the sale of 'fine cutlery, staples and French & English fancy goods'. He was succeeded by B.W. Thayer in 1844 and became known as B.W. Thayer & Co.

First of this grind I have. Looking forward to the shave.

That is a very unique grind, I have seen a handful of them but never owned one. Your razor is in very nice condition, hopefully it shaves as good as it looks:)

Wow, that is one fantastical blade! You did it some justice with the restore too. Excellent job!

Most inlays of that type had posts that went through the scale. It needed to be installed before assembly.

Great looking razor...nice job!

A parser is what you need for the escutcheon (The Forgotten Art of the Two-Legged Parser by Geoffrey Tweedale), (http://www.petermcbride.com/parser/)

Looks great!

Nicely done Karl! Great looking blade... :tu

Beautiful scales and a very nice mirror finish.
