[Milsurplus] SRR-13A - Tune up tools question

[John Hutchins]

John -
The front panel has a slant V in the top, the sides are bent also you 
can see the handles are kilter-ed in.  I have to some how pound out the 
V dent, pust out the left/and / right side then  reform the front panel 
profile.   I think that can keep the "profile" can be acheived by making 
a wood block out line.  Any how need to unmount all the knobs/ switches/ 
lamps and meters.  A un planned project for sure.
