Great minds think alike.
Years ago, I bought a bag of 100 P-38s for about $20. Gave away a bunch to friends and coworkers, stashed a bunch around the place and in all the vehicles, and still have maybe 50 in the bag.
Ha! I thought about mentioning P38s-51s in my post. I bought a handful of 51s at a surplus shop. They were stamped US but I can’t believe they were authentic. The hook that goes under the can rim bent the first time I tried them. They were cheap soft metal. I wish I could find the real thing. I had planed to give them as gifts to my young nieces/nephews but would have been embarrassed if I had.
