[R-390] Filter inside dimensions

[quartz55]

I've posted a pic of the dimensions I measure of the copper cup, wire, bobbin, etc. on photobucket if anyone is interested.  Just to keep track.  It agrees with G8OAD's dimensions within 1/4".  Drawing is not to scale.  Wire dimension was taken from when it came out of the filter.
