Missing grade?

[Joseph white]

Ok yall im a newbie here and to parkers. I bought a parker on a local online auction last week. I have looked into the information here and in other areas and have a decent understanding of what I have with the exception of the grade mark. I've taken and posted a bunch of photos here to see if anyone else can help me out with it. I will post any other pics needed if you ask. From what I know right now I have a 1883 twist barrel, size 3 frame with a barrel weight of 58. If any of that is wrong please let me know. Also if anyone would be willing to spit ball a value I would much appreciate that, and I know it would be a unofficial one, im just looking for a rough idea to see if I over paid lol. After I sort all this out ill be posting more threads on the restore or not to restore question. Thanks yall and I look forward to working with ya!
