Cool! 60/40 was what was used when I started back in the 70s. It wasn’t until I got to the military work that I found 63/37 eutectic solder was their standard for high reliability work.

Some more from an ancient time......the most interesting is probably the original pure silk insulated wire (10 x 0.01 mm2 cores).

Front side of old 60/40 solder box……..3 cores of flux.....so multicore...
I think Ersin still is a solder brand......

Here are some pictures of a 300 watt (at an unknown but high level of
distortion) solid state audio amp that I built in high school.

Love the blower.
