Button Collectors: HR Company Button...

Just wondering of anyone knows who the HR Company is on this button
(see link)

I recently excavated this button while out metal detecting and am
researching who the HR Company is. It's an old button. More than
likely early 1900's judging from my other finds at the same site.

I was thinking H&R Firearms company, but why would they make a garment
button? I'm missing the buttons' back. However, I did recover a work
clothes button nearby that was missing it's front. So, I'm leaning
towards a work clothes button. But, I just can't find who the HR
Company is.

Any information would be most appreciated.
Thanks.
