I do not know how the Lyman D-7 measures up to (pun intended) to the M5, but I have a D-7 I purchased new back in the 1970s for $17.15 from the Ft. Riley Rod & Gun club. It still has the price sticker on the scale itselp plus I have the box. No intentions on selling it, but I am curious how it compares.
Let's see that photo get over to "pictures of your reloading bench/equipment". I like the old equipment but photos are far and few between.
