Where 19500100 is used for date_original

[jrgriffiniii]

Values for the fields date, date.original.display, date.original.search, date.approximate, and date.range can also contain problematic values between various projects:

• 1930? (beyond-steel)
• 1925,1926,1927,1928,1929,1930 (cap)
• 1921-1929? (cap)

Most of the ranges specified by cases such as 1925,[...],1930 appear to be contiguous
