I've got a number of these standard arm pins in my possession and thought I'd offer some here, in case someone could use them. These saw use along every CN line in Canada. All are more or less a uniform shape and size. Measurements are 8" tall by 1 3/16" wide at base. The threads are standard 1". Some have creosote residue on the threads, as it was standard here in Canada to use the stuff to help preserve the wood and also hold the insulator in place.

I'm asking $15 USD plus actual shipping from London, Ontario for the ten shown here. 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.
