tin/lead bar identification? Plz help

[hickory kid]

Well I’m hoping I got a good deal on these bars. I was told that they were all 60/40 bars but they don’t have any markings that say that. I bought 2 different kind of bars but they both measure 13 long x 3/4 wide weight about 1.6 lbs each. The first bar has national lead co molded into it and 33 CE stamped into it. The second set of bars doesn’t have any name but have CE7 74 stamped into it them. Can someone help me identify these bars? Thanks

Hickory, welcome to the forum.

Do you have a means of melting those bars with a thermometer constantly monitoring the temp? If they are solder alloy they will melt at less than 400*. Also, if they are 60/40 you should be able to bend them pretty easily. Just from the looks of them I would have paid up to a dollar a pound for them.

Back in the 1980's I spoke to a representative of National Lead Company who reported:
NLC bar label
111 = 50% Sn (Tin) and 50 % Pb (Lead)
666 = 40% Sn, 1% Sb, (Antimony), 59 % Pb (lead)

Additionally, I had some bars 63/34 which are a eutectic alloy containg 63% Sn and 34% Pb.

You like to buy like I do!

As far as their actual value with tin being at $9.43 lb spot and lead being around $1 a lb. If it was 50/50 and you got them for under $5 each, you did ok. If you got them for a $1.60 a bar or less you can consider that you did very well.
