Herschede grandfather clock serial number?

the serial number on the clock is 01933 I look this up and dint find any number that matches any thing that starts with a 0 do I drop the 0 then 1933 tells me that it was made in 1914 when I look it up. I inherited this clock. my family thinks the clock is newer and isn't worth much but I thought I would look into it any way. thanks for any help
