Tinabug

I need help with a decision, This machine is $55 but I don't know if I should buy it since the bed is cracked, otherwise it looks to be in pretty good shape. From the pics.
VERY RARE HARRIS "S" HAND CRANK SEWING MACHINE FROM ABOUT 1930 WITH ART DECO STYLIZED ROSES. Made probably by Haid & Neu for Harris which was a large London distributor. This machine dates to around 1930, the stylized roses are typical of the Art Deco style. Note the ruler inlaid in the base and the recessed hand crank, with the bobbin winder being directly driven from the gear wheel. Includes a lovely locking case with key. The base is cracked, so this may not be usable as is, but it is lovely and makes a wonderful display piece
