Oldfoneguy what I have is Weaver base 5 for large ring 1.410 and Weaver rings 49350
I found the above after an extensive search. It seems only the high and high long ring sets are currently available new. You need the 1" low ring set which show as available on the above site. They have several varieties including NOS and used with various states of finish wear. They can also be found on ebay almost all the time. The set you have are high standard length and are incorrect for your base.
