From a former oboist there is this:

I have a 1991 Loreé oboe, AK model, serial #JU53 that I’d like to sell. It has a crack repair in the top joint, and a Philadelphia D key (installed by Robert Sorton – professor at Ohio State). As you can see by the photos, the silver is in great shape.

Contact me, please, if you are interested, and I will connect you to the seller.
