All insulators are actual size w.r.t. each other in the photo. On the right of the picture are two distinctly different Brookfield signals that are hidden inside the CD system. SInce the CD system consolidates shapes, these two pieces are under the 162 listing. Most of the hobby probably has not seen "134/162 hybrid." Some people are familiar with the "133 with an inner skirt (likely b/c it is known in SCA coloring).

These are hidden b/c the CD system says a signal with an inner skirt is a 162. So although the one is shaped just like a 133, its inner skirt hides it inside the system. The 134/162 hybrid actually does have a twin in the hobby. There is a KCGW signal with the exact shape (Possible connection?). But most collectors have no idea that these exist.
