OK then the 11.oclock is more of a collectors lens and the 7.00 to collect or use
There are a lot of the standard 7.00 oclock lens for sale,in fact i have one on my 11C
I wont buy an 11.00 oclock Hektor then,i thought they might be special as the ones ive seen cost up to twice the price of the 7.00 oclock Elma
Let me explain.
Elmars and Hektors are totally different. A Hektor is a F2.5 design, an Elmar is F3.5. Back in the 1930s that was a big difference, only a few lenses were faster. The Hektor is a classic because it was Leica's first design meant to be faster than their first lens, the Elmar. Faster lenses are usually more expensive than slower lenses. The Zeiss Sonnar 50/2 versus 50/1.5 for example. Or the Jupiter 8 vs 3.
Being a different design, they will have a special look, as all different designs do. 56,540 Elmars were made for Leica A cameras from 1925 until 1932. In those years only 1,330 came with Hektors. Over the years, millions of Elmars were made, if someone wants a lens that looks different, from the same era, and is uncommon, they will pay more.
There are varieties of all lenses. A nickel Elmar is more expensive than a chrome one. An 11 O'Clock Elmar is more expensive than a 7 O'clock one. A "red" Elmar is more expensive....and so on, based on rarity or whatever people believe.
So, a Hektor, a first fast design, and an early Leitz lens, and a Nickle version, and an 11 O'clock version, will be the rarest of any of them. Supply and demand make it more expensive. It will take similar pictures than a later one of Chrome and 7 O'clock. So it's a user and a collectible.
