Here is the largest Ogee in profile.
And here it is in use, its funny it still works, and I haven't sharpened it in at least 15yrs.
This is the moulding that it forms.
The cockbeader(probably not a word).
And the Ogee
This is why I suspect this plane would be of more use to a joiner, I think its for forming glazing bars for some of the sash windows in Norwich, I've seen them very similar, and the plane was made by Griffith's of Norwich too.
Thank for looking, I hope its of some interest?
