As for the images, are you uploading yours directly to this forum? I'm uploading mine to Photobucket, then including the direct image link code in my post between the pair of IMG brackets that I type in. More work, but you've seen the results.
I wondered if it might be something like that. I never noticed that you can't edit old posts either.
Here is the same image of mine posted earlier but hopefully the image looks better.
Perplexed, what date is on your barrel?
