Need help identifying a old button

[blong10]

I was out metal detecting today and I found 2 of these old buttons. It reads Stanley Warranted Wills. For some reason the Warranted is backwards. Could anyone help me identify the age of this button.There is nothing on the front of the button. PLEASE CLICK ON THE IMAGE IT LOOKS BLURRY ON THE WEBSITE.

I can not find a single reference on your button nor have I ever seen a Will Stanley Warranted button. I am perplexed. I don't see it listed in CW Buttons on either side But appears to be mis to late 1800's. I hope a button expert can chime in and know something about this guy. I am curious.

I would guess your backmark is British. The date range would be from 1790s to 1840s.
