[AMRadio] Simpson Meters

[Bob Maser]

I am trying to find a replacement body for the plate meter on my 20V-2. The 
inner guts is OK but the front face is partially destroyed.  When I look in 
the user's manual, Collins does not identify the model number of the meters 
but they appear to be Simpson model 27.  I put a want on QTH.com and there 
has been several responses but when I send them a picture of the meter they 
say that their model 27 has extra vertical stripes in the lower corners than 
mine do.  Can someone tell me which Simpson meter I should be looking for?

Thanks
