I just received 2 1lb containers of H4350. One had no lot number. I called Hogdon , Luke said that the shipment was huge and they were probably the same. I was hoping if anyone got some , they might post what lots they received. My marked container is 1032420 7175. Not fond of mixing, but I've read a lot of archived posts here saying it would probably be okay. Hope everybody and their loved ones are staying safe , looking forward to a happier time!
