These unembossed rounded base/MLOB CD 143s are notorious for coming in a huge variety of colours. This type of CD 143 saw a lot of use across much of Canada in the late 19th century, and as such was made in large numbers in multiple molds and various colours. This group of 4 oddballs are all somewhat unusual colours. These RB 143s aren't especially popular in the hobby, and there are some good ones in this group. If you like early Canadian glass then you likely won't regret buying this set! From left to right:

1.) Drab light green. Sort of a washed out shade that is undoubtedly the most common of the group. It has some minor milk and bubbles. This example is nice and shiny. It has three small base flakes on the inner base edge, two on one side that are 7 mm and 5 mm wide, and the third on the opposite side measuring only 3 mm wide.

2.) A crisp, vivid lime green colour. This mold style and colour are much, much harder to find and likely earlier than the example at far left. This example came from a farm auction near St. Thomas, Ontario, and may have seen use on the nearby London & Port Stanley railway telegraph circuits. This example is fizzy and has some nice fine milky wisps spiralling around the crown. It has some roughness and a couple small flakes around the sharp inner base edge but is overall in great shape. The colour is really quite vivid in natural light.

3.) Another surprisingly scarce piece: a sort of "bright light aqua" in the same mold style as the lime green example. For being an aqua shade, this particular shade looks pretty nice. This example has a pronounced surface whittle and some carbon swirls in the dome. Nice and shiny, with a 15 mm long flat base flake on one side and some other much smaller inner base edge flakes. It also has a 5 mm fisheye bruise and some scuffs on the side of the crown. Overall it looks good, and I'm probably making it sound worse than it is.

4.) A very odd shade that falls somewhere between "light grey", "steel blue", and "light aqua". I'm struggling to put my finger on the name of this colour, so I'll just leave it as a "tweener". This one has a 3 cm base bruise and an associated 2 cm tall vertical crack in the skirt on one side. It also has three BB pings - two on the crown and one on the skirt, ranging from 2 mm to 7 mm wide. It displays well from one side.
