Ronvella,

That file for express sights was listed in their catalog during the 1980's before anyone knew what a website was. At the time I had the paged marked and circled it in red ink. It was on a page with the various express sights they offered. Unfortunately I can't remember who manufactured the file.

Before I posted my response to 500grains, I looked over the Brownell's website to see if they still sold the same file and could find no listing for it.

Richard.
