Joe,
Thanks for sharing your nice photos of your new HSc example. "Warbird" is the authoritative resource on the subject and he can provide you the best answer that you seek. I enjoyed seeing your photos and had to chime in with my congratulations to you. Have your checked to see, if the slide and barrel have matching serial numbers? If you have trouble finding them, just say so. Just a question. What is on the bottom of your mag base, if anything? Also, I like your choice of cleaning tools as seen in your photo. Where did you get those nice picks?
Jim
