Ground vs Factory Sealing Surfaces

[foxfirerodandgun]

I have the Red Book #13 for fruit jars and am trying to pin down the ID's of several Mason, (not Ball), Pat. 1858 aqua quart jars. I know that they were made up to around 1910 or so with the 1858 Pat. date but there are so, so many different ones that after an hour or so in the book I have temporarily given up How do you tell the difference? Thanks

Post some pictures and someone will be glad to ID them, BTW I only use red book 12 and lower as well as " the fruit jar works 1 & 2" as in 13 there have been from my understanding a bunch of jars removed.

Thanks. Here are some pictures of two of the aqua, one-quart jars. Both appear to have ground sealing surfaces.

the first appears to be #1989 in the red book, the second looks like a # 1920 according to " the fruit jar works" most ground lip jars are pre 1900 and made by various makers.
