Help ID Godin(?) Antique Grate

[Stephatch]

I’m hoping someone here can help me identify an antique cast-iron grate I have had for a while. I only have the grate, not the stove. From what I’ve found it may be from a Godin stove, but I’m not certain.

Length: ~12 inches

• Markings (on the back): “11 2 20” and “J A G O B S” (could be “B5” instead of “BS

I'm wondering which model/era stove this grate may have come from, whether it’s definitely Godin, and any ballpark idea of value just for the grate alone.
Thanks in advance.
