I am trying to help a friend restore some old wooden window frames from 1915.
Most of them are in pretty good shape, however there is one where the bottom rail is half rotted.
It will need a new piece and I am trying to get a name or specs of the profile.

This is a 6 pane window and the center rails go all the way across.
The center stiles are short and I was able to remove one as a sample.
Here is a couple of pictures and I am hoping someone can give me a name of the profile, even better if there was a place where I could get a detailed drawing, so I might be able to reproduce the profile for the bottom rail.
The overall dimensions are .75 wide and about 1 11/32 tall
I believe the top is 5/16 wide the second step is 9/16 wide.



I can cut the rabbits (for the glass) on my table saw or router if needed.

Any help is greatly appreciated.

Mike
