Nitto B123 are 170 drop and come in 34cm wide or more but you'll need a 25.4 stem or shim to 26mm.
If you can't find any in the UK ATM ( I could only find 38cm or greater with a quick look) then you might have to get direct from njs export https://www.njs-export.com/collections/handlebars/36cm?sort_by=title-ascending
