Help Indentifying C.C. Harrison Peztval Lens & Voigtlander Collinear Series II No. 3

[Primo I.]

Hi everyone, I am posting this thread in the hope that someone out there may be able to help me identify this particular C.C. Harrison Peztval type lens but more importantly, some markings (roman numerals) I found as I took the lens apart to clean.
I was extremely fortunate and lucky to have gone to a photography related liquidation on both Friday and Saturday that a friend had called me to attend.

Aside from countless lens caps, hoods, shutters and other misc parts I picked up (all large format), I also managed to pick up 20 lenses. This was the day that I always fantasied about that I would be able to somehow buy some really nice things for very cheap. I kid you not, I spent $550.00 in total and the only reason I believe I was so lucking was that it rained these two days and it was miserable out. I guess people decided not to venture outside because there wwere only about a dozen people at any given time throughout the two day sale.





Some of the lenses I bought I am familiar with but there are many that I do not know. I will be reaching out to the forum to help me identify them as I go through each one over the next week or so.

The first one and the one I am really excited about is a C.C. Harrison Pretzval type lens which I saw from the corner of my eye and immediately picked up and put into the basket while I tried to control my excitement. I started to take it apart to clean it thoroughly and I noticed something odd (at least it was odd to me but may not be to others) after removing the front and rear elements, I noticed at one end of the barrel along the inside rim were Roman Numerals that were etched in. The numerals are "XVIII" or the number 18.

I really didn't know what to make of it and there is nothing else on the lens other than the following: "C.C. Harrison New York" and above that what seems to be the serial number for the lens "4386".
I am attaching a couple of images of the lens, one with the description and the other image is the section with the Roman Numerals. If anyone out there can help identify this, I would sincerely appreciate it. I would also appreciate if anyone can also identify the lens itself. I've never owned one (only dreamed of owning one) I have only read great things about the Lens maker on this forum so I am pretty excited about it. The glass is pristine, maybe a slight wipe mark but that's it, the glass is free and clear of anything you can think of and the housing is just dirty but no dents or marks. I bevel it may have had a brass hood but I was not able to find it during the sale.


The second lens is a "Voigtlander Collinear No. 57272 Series II No. 3 - f/1:5.6". I am familiar with Voigtlander but I do not know this particular lens. Any feedback would be appreciated. I am also posting two pictures of the Collinear to ask if anyone is familiar with it and any feedback regarding its capabilities. The glass is in pristine condition, clear and transparent. The housing shows its age but clean with no defects or dents.


I have about 9 lenses I am not sure about and would like to bring them to the forum in an orderly fashion so I can get help in identifying them and more importantly, get feedback from anyone who may have experience with them.
Thank you all ahead of time for any help you can provide.
