This one was long overdue. Already in 1936 Kurt Weitzmann described a lectionary from the Skevophylakion (Sacristy) of the Lavra Monastery on Mount Athos. It seemed to have gone under the radar here at INTF. Now it is known in our checklist as l 2461 (no images available).
With thanks to Tommy Wassermann and recently Robert Nelson who have mentioned it.
