The Brookfield No. 36 on the left is a CD 162:

[240] (F-Skirt) BROOKFIELD/[Number] (R-Skirt) No 36 RB

The one on the right is a CD 134:

[200] (F-Skirt) BROOKFIELD (R-Skirt) No 36/[Number] {Note 'No 36' style number} {This is a CD 162 with no inner skirt} SB

Both have the style number '36' on the back. In fact, they're identical, except the one on the right is a slightly earlier piece and does not have an inner skirt.

Easy to miss! I had placed both of these alongside one another in a box of 162s. When I pulled them out a short time later, I was very pleasantly suprised when I discovered that one was a 134.
