I have been lurking for a while, but this is my first post.

I am in the process of purchasing a Wolf 30" gas range on Craigslist for what sounds like a pretty good deal to me. The seller says that it is 3 and 1/2 half years old, but was only used for 1 and 1/2 years and has been in storage ever since. It looks like an r304 from the picture, but I have not yet seen it in person.

Here is my question. The seller says that it does not have a convection oven. I think he may be wrong, but I can not find the specifications of previous Wolf products. All that I see on their website are the current models.

Does anyone know when Wolf started selling the 30" All Gas ranges with convection ovens or where I would look to find the specifications of prior year's models?

Thank you.
