I did a search on digitalfire which has almost everything and it was not there. I then did a global search and one suggest 3518 through to 3525 were related. From what I have seen, all frits in the 3500 range are lead based. Here are 2 which are close in number with similar, yet very different compositions. Sorry, I know it isn't much help but perhaps there is something to be grabbed from it.
