Is a CAT 304 at auction now?

Are the CAT 304 hammer prices free to read?

The oldest sale of every model is free to read, and so is every hammer price under the site's floor. Every other hammer price opens with an account, one sale at a time.

Hammer prices are what the auction house recorded when the lot closed, before the buyer's premium, in the currency of the sale. A sale listed on a house's own site and on its platform counts once. Doubt a figure? Open the sale and its listing is linked there. How prices are recorded.
