I've been using a B&M measure with a plastic powder tube for 3 or 4 years now and really like it.
A couple weeks ago I found the brass tube version at a local gun show. For $20 I couldn't leave it behind. It seems to be an older version. It has a unique faceted glass window. Rather than the flat glass of my other one. At first I thought it was a home made replacement. But it it is so well made that I wonder if it is the iriginal glass. What do you guys think?
Can anyone date these?
Thanks, Steve
