Dallmeyer No. 3 Rectilinear specifics?

[goamules]

I just got a brass Dallmeyer number 3 Rectilinear. I've gotten the serial number matched to 1885. I believe there were two types of rectilinear, this one does not say "rapid". One person with the serial number list suggested it is a "wide", I guess as in wide angle. Does anyone know anything about this lens? It has waterhouse stops and no marking as to coverage. I'm thinking I could use it for landscapes.

Maybe this page can help you a bit. Sometimes really old information is tough to find on the internet. When I researched my old Holmes, Booth & Haydens, I ended up at the downtown library to figure it out.

Thanks and you're right. I'm finding very little about this lens. I think it is made for landscapes, and may cover 13 x 18. I'm sure it will work for half plate!

I am not certain, how your Dallmeyer No. 3 differs from mine which is marked 3D, but mine is also maked as a 12x10 f6.3 lens. The rear cell also has 4 notches which are used as marks to measure a varying degree of sharpness/difusion.

Thanks, this one is different than a 3D petzval. I don't have it in hand yet, but it's short and squat in the auction 320207713485 picture. It says "rectilinear no. 3" and has a US patent and date.

With an 1868 patent date and an 1885 serial number, it would be a wide angle Rectilinear. The "Rectilinear Landscape" was patented in 1887.

If it's the same as was sold in 1888, No. 3 would be a 13" lens for plates up to 18x16".

Thank you Ole, good info as always.

Got the lens, looks very wide both by the hemispherical objective, and held up to my ground glass. Nice glass.

It's good to see that it does indeed look like a wide-angle rectilinear. :)
