The intrigue of the volunteer plant. You don't if it will make "chicken salad" or "chicken $#@%" Hope it's a good 'mater!

There is a red submarine, and it is RL. (Which is what your plants in the second picture appear to be, I think Seysonn was looking at the Basil leaves in the background of the first one.) There is also a red pear (haven't grown it) but the pics I have seen of it tend to be more narrow at the top: Red Pear. I've also seen a couple of other tomatoes with Red Pear in the name, but they aren't shaped anything like that, more knapsack shaped. What you have looks more like red plum, but as Dave said, no way to know for sure. You may want to contact Seeds of Change and let them know what you are getting, I'm sure they'd like to know. And if anyone else has gotten the wrong type from their SM seeds, they may want to pull the stock of their San Marzano. Of course, you may have just gotten a stray seed. It happens.

Yes it is often referenced/linked here. Another good one is the TAMU site. Here is a link that might be useful: TAMU - Tomato Problem Solver

I had the same spotting on my tomato plants in early April. Finally decided it was caused by cold weather and high winds. Temps were down in the high 30s and low 40s for several days. It's all gone now - just went away by itself when the weather warmed up. Here's a link that explains it better: https://plantclinic.tamu.edu/2011/05/10/tomato-woes/
