So I cleaned up a box of old moulding planes and came out with a great Ohio Tool No. 47 dado plane. It cleaned and sharpened very nicely but it is missing an iron. Hard to see in the picture but there is a secondary iron in front that leads the cutter. In the picture you can see the mouth just under the stop. I assume it’s a nicker??

Anyone know if where I can find one? Or have a picture? I’ve looked on eBay but because I don’t know what it looks like I can’t really figure out if anything listed would actually work nor can I fabricate a new one.

Barring a pic, I’m going to get some steel and a file and fake it.

those wooden planes were generally hand made and the cutter was custom to the unit. If it needs a blade, you will need to make one.

If it were me I would start with a file, and put it in the oven at 450 Degrees F. for half an hour. This will give it the correct temper. (files are too brittle to use without retempering.)It will be a light yellow brown when you are done. (straw) It should be about about Rc 63. it will not file well. but will hold an edge and be less likely to chip.
Then I would sand top and bottom to remove the teeth, after that, grind it to shape

-- nice recovery, They should pay extra for that mistake, Eric E.

I was afraid that might be the case. Any idea what the blade looks like?

From your description, it sounds like your knicker blade may be like the one in this discussion:

Edit: I forgot to add: If the blade is like that, you might be able to make it out of a blank from Lie-Nielsen:
