Tejano,
Here is another pic of the Talley compatible rib grooves with my Talley peep sight on my Simson Suhl DR.

The gun maker that did this also made and sold such rear ribs to to other gun makers and gun smiths.
The only such gun maker that I know that bought some is W Ellis Brown in FT Collins, Colorado.
