Bordello - category

[forest341]

I was looking at the 2020 WC results and saw the entry for "Bordello". It doesn't appear in the rules booklet, that I can find. What exactly is it? Is it for using our more conventional semi-auto pistols? And is it just a exhibition type entry?

it is exhibition only and shot with carry type firearms. shot on the field pistol targets and no sight changes are allowed.
