This video from oorail.com looks at both the rail type and sleeper built type buffer stops from Peco. It compares them to the Hornby R083 type buffer stop. The video shows how to build the SL-41 (Sleeper type). The video shows a few real life examples of the rail type buffer stop at Exeter and the resulting painted Peco SL-40 rail type buffer stops to match those photos. The video also shows how to enhance the SL-41 using medium ballast (cinders) and mine run coal from woodland scenics. The video wraps up with a few shots of the new buffer stops on the layout.
