Help ID and Dating Lift the Dot Sockets and Clip Hardware

Hello everyone, I am new to the forum and was hoping to learn from the members here on some hardware I recently acquired.

I have acquired some Klikit Pull Six Star Sockets and Backing plates. I have two versions -- different prongs and different radius metal. I am hoping someone can tell me about the dates these would have been made.

The next items are some hook clips with manufacture marks. I am looking to get some information on who the makers are and approximate manufacture dates.

Thank you for taking the time to read my post and to provide your knowledge!
