Steve Bringhurst's BC221 Crystal Set
Here are some pictures of Steve Bringhurst's BCB set, built using a WWII BC-221 frequency standard. The vernier on these sets is smooth and precise, and the cap is of the highest quality.
This is his TK-2 set (Tuggle/Klase Version 2). The band is split into two segments, with a fixed cap added the the main tuning cap to extend the range to the bottom of the band.
