One of the experts here may correct me but I'm thinking it's 40% tin.

The first number is the tin content.

It was a mistake. Where I work, someone ordered 60/40 solder bars for a project and asked for 60% tin. Wrong !!!!
They were going to throw it away, but it only made it as far as my trunk !!![smilie=1:
The more tin the lower the melt temp.
If it's 60% tin melt should be at or near 350-375 deg. F.
If it's 60% Pb then the melt should be nearer 400-450 F.
Good Shooting.
