Hey everybody. Can you please give me some expert advice here. Am I looking at doubling on this 63 here. Look at the images and share your thoughts. Thanks in advance.
Your photos are too small for me to see anything. It's helpful if you would post enlarged photos of the areas in question. Thank you.
