This is probably a stupid question but, where does this one fall in the CD chain? It is in the middle of a CD 134 and a CD 133 but it has a flat top, measures 2-1/2" across and 3-5/8" tall. It is marked W.Brookfield with New York on the back and 2 raised dots on the dome. Is it a 133 or 134 variation or a 133.1. Just thought I would ask. Thanks!
