Welcome to the forums, Marcus! I agree with newbroom about the circled "B" on the stem, but the stamping on the shank is a mystery.
Good job getting the pic loaded, there are many here that don't get that far. If you ever want to post a pic in a thread, you only need to do the following couple steps.
If you're on a desktop, right-click your picture and select "Properties". You should then see this dialog box:
Go to the Address (URL) and highlight the ENTIRE URL. It is multiple lines, so it's easy to only select part of the URL. Copy the entire URL.
To post your image, click IMG and this box will open:
Paste in the URL that you copied from your album, being sure to overwrite the "http://" that was automatically populated.
You won't be able to see your pic until you hit "Send Post", but if you followed the steps right, you should end up with this:
It's easiest to do this if you have two windows open: one for composing your post in the forum and the second for access to your My Account/album.
This process is a bit different on a smartphone, but as long as you can copy the pic's URL you can successfully paste it into the "IMG" function.
Sorry for kind of hijacking your thread. I hope this helps and again, welcome!
