Source for Asymmetric Oak Entry Door Threshold

My house was built in 1955. The contractor installed 4.5" asymmetric oak thresholds on the side entries and a 5.5" asymmetric threshold on the front entry. I would like to replace them. They are worn, checked at the ends, and badly discolored.
By asymmetric threshold I mean, for the 5.5", a profile (starting from the inside out) which is a ~1" rising transition to the under door portion (profile convex then concave), a 1.75" under door portion which pitches slightly to the outside for drainage, and a 2.75" outer falling transition, similar to the inner transition, but with a long down sloping flat section in between the curves.
Does anyone know of a source for such a threshold?
Thanks,

Easy enough for a carpenter or millwork shop to make them for you. Sketch it up, fax it over to the millwork shop and have them give you a price. A competent carpenter could make them on the job with a tablesaw and a hand plane.

Yeah. Take the old one out, and either machine/whittle one that looks just like it, or take it to a custom millwork shop. There is no such thing as a 'standard' threshold- every maker rolls their own for each model/series of door they come up with. Even 'universal' replacements usually end up having to be field-modified to fit. (BTDT). I suppose matching a 52 year old style is possible, given the right small-town lumber yard or door specialist, but it ain't real likely. I'd suggest checking door aisle at local Habitat ReStore or archictectural salvage place, but anything they have is likely to be as tired as what you want to replace.
Are the rest of the door assemblies anything special? (ie, custom size, round top, special detail and trim work, etc?) On a 1955 house, I would <seriously> look at switching them out with modern insulated and weather-resistant exterior prehungs. Unless you go 'designer', they aren't THAT expensive, work a lot better, and are a big plus if you plan on selling the house in next five years or so.
