Found some insulators...

[Barrett]

For anyone interested in what Rick has turned up, I am attaching a few to these next few posts.
Rick - no problem on the help. That is what this forum is here for! Unfortunately, most of its members are busier than usual these days (myself included), so we don't often find the time to indulge in internet insulator chat.
Your green Diamond pony is a pretty common piece. It is also a telephone one - a much earlier counterpart to the Dominion No. 9s that you turned up. Much more beautiful, though. It probably dates from close to the turn of the 19th century, or up into the 1910s. It is a product of the Diamond-Flint Glass Co. These come in an inimaginable range of colours, as you will no doubt find out! Taking one look at the page of listings for this embossing style will give you an idea of how many shades there are out there. I count 53 different colours, and that is no doubt not including some lumped-together colour groups, or some possibly unlisted, unheard of colours. If you are intending to collect these, you have some work ahead of you!
The other two very light green Diamond ponies are the same style and embossing, they are just an ice green shade. These are also quite common, though I have always liked them!
The purple example is a different embossing listing (It has a diamond on the reverse as well, right?), but is the same style number. It is probably worth something like $20-30, due to the desirable purple colouration. Really the purple examples are quite common as well, people just really like the colour!
The B.T.Co. of CAN piece is again the same telephone style, but marked with the "Bell Telephone Company of Canada" abbreviation on the front. The pieces in that thinner-skirt mould that comes in shades of green aqua and green were made by the Brookfield Glass Co. for use along Bell Telephone lines here in Canada. Certainly a cool piece!

In case you are interested in learning how to upload photographs, here's a quick walk-through. When you are in the post-typing window, you will find a list of options immediately underneath your "Save, Submit, and Preview" buttons. Immediately beside the "Options" tab is an "Upload Attachment" tab. This is where the magic happens! Simply browse for the file name, the same way you would in facebook, and then click "add the file". You can upload 3 photographs per post, and I believe they have to be below a certain size (Bill, can you refresh us on the size limitations?). Give it a shot with some of your other pieces!
All the best!

As well, look for real small numbers on the backs of the Diamond ponies. The ones at the base (forward and backward variations) are easy to spot, but the real small numbers right under the lower wire groove are a little tougher to spot. Also LOVE the HUGE solid dome on that B.T.Co. piece. Hope to find some ponies while I'm out here in Calgary, but probably Rod Bushfield has them all russled up.
