Stanley No. 71 antique router plane.

Please note there is a “B” on the back, as shown in the pictures.

I have not tried to clean this piece or use it.

I believe the key is supposed to move, but it does not move currently. I have not attempted to loosen it with any lubricant. There are no known cracks or broken areas.

Thanks for looking.
