Someone is still making slide rules

Bill - I have several of these Sama & Etani pocket circular slide rules, each with a single insert; I have an ST, CE and 2 others w/o labels. Also, the backs of the rule body contain either a Periodic Table in the classic layout or a simple listing of the elements (older unit).

Does your rule allow all 3 inserts to be inserted at the same time? I've never seen a rule that accepts more than 1 insert, so I'd be interested to see how that one holds 3, if that's the case.
