Mellotronists

no, i have no particular reason to dislike someone named "specs".

what i am looking for is:
does anyone know the specific specification for some of the screws
on a mellotron m400?

specifically:

the pair of wood screws that hold the control panel in place
[length/thread pitch/diameter]

the four screws that hold the bottom plate on the control panel
[length/thread pitch/diameter]

i need to get replacements for these.
someone at our studio has lost these screws.

i may just steal the damn thing to prevent any further harm
from coming to it. protective custody might be invoked.
they just can't leave the damn thing alone, and everytime
they touch it they screw [or unscrew] something up on it.

thanks in advance, as always,
jeff
