So I've got an '04 Brommie that I'm rebuilding at the shop. Went to pull the grub screws out to install the carrier block,and it turns out they're plastic. My little screwdriver(that I've never actually used on a screw,just as a scraper and pry tool) didn't fit. Swiss Army to the rescue.
For comparison is a modern steel one. Also installing a modern suspension block and post QR so the bike stays unfolded,and modern brake levers so the cust can find replacement cables. Surprisingly,the old Sachs Torpedo was properly adjusted.
