400mm f4 Charles Shepherd Questions

[rosshj]

Hi!

This is my first post here. So hello 👋

I'm in the hunt for a lens that will cover 8x10 all the way up to 14x17 for portraits. 1:1 and waists up.

I have someone who is offering to sell me 400mm f4 Charles Shepherd Petzval threat is in pretty amazing condition minus a chip on the outer edge of the back element. Don't believe that will affect the image though.

I have a couple questions I'm hoping people here can help me figure out.

1. Do you think this lens will cover 14x17 for portraits?
2. What do you think is a fair price for his lens?

Thanks!!

Here is more about the lens:

• Made between 1855-1857
• It's 25cm high and 16cm width (lenshood)
• The glass diameter is 10.5cm
