My Sarco order arrived. The magazine seems very well made and heavy. Marked 2/1001 on the side, aluminum base marked 6849 with a 2 above. Should be a serviceable magazine until I can find a more correct magazine for my 41 byf.
The tool looks like it was made last week.
Don't have a digital camera so no pic. I have to find a magnifying glass. Looks like there is a faint SA in a box, and to the right of the SA there's a mark that looks like a large 7, with maybe some faint mark under the part of the 7 at the top going to the left.
