Hi everyone,

I posted this recently on subreddit r/colloidon, and a user suggested I post this to LFPF. I found three lenses in the crawl space of a home I just moved in to, and I was wondering if anyone has more information. I'm particularly interested in building a large format camera and bringing these lenses back to life but am unsure if these are for 8 x 10 or for a 20 x 24 camera (I am aware that there are a couple of posts referencing C.C. Harrison. I have also consulted CNUM, Camera Eccentric, Keh.com, etc. per the 'stickied' posts).

Here are specifications for the three lenses, images below.
1. Measures 8" tall, the front element is 3" in diameter, there is no iris or aperture blades inside, but a slot which allows for a Waterhouse stop to be inserted. The inscription reads: 7862 C.C. Harrison New York.

2. Measures 7" tall, the front element is 3" in diameter (maybe an 1/8th of an inch short?), there is no iris or aperture blades inside, but a slot for a Waterhouse stop to be inserted. The inscription reads: THE PORTRAIT Rapid Rectilinear No. 718 18 x 22 to 20 x 24 O.H. PECK Sole Agent MINNEAPOLIS. The brass hood is removable. This one came with a Waterhouse stop. From what I understand, O.H. PECK was the dealer/distributor.

3. Measures 4-1/4" tall, the front element is 2-1/2" in diameter, again there is a slot for a Waterhouse stop. This one does not have any inscriptions.

From what I understand so far, these are all Petzval lenses? Does anyone have any more information? value?
