From left to right:

U-1445 Gaskell & Grocett. 1/2" wide chip on the rear upper wire ridge.

U-1565 Bullers GPO w/ admiralty arrow marking. This one is an odd sandy brown glaze. Unfortunately most of the inner skirt has been chipped off so it no longer sits its full height on a protruded inner skirt.

U-1548 (?) "Slimline pattern". This one is marked LMS and has a Bullers mark with a 1933 date. It looks to be mint and has its original soot.

Now asking $20 USD plus shipping for the three insulators. I'm always happy to trade for early Canadian glass or Canadian-made porcelain insulators. I accept PayPal, or personal cheque from any member of ICON or any collector with whom I have dealt before. Please feel free to contact me with any questions or for more photos, and look through my other items or unsold sales stock to combine shipping on items.
