I'm going to guess that's normal?

Your roentgens meter is slightly different than the screen used meter. It looks like the face of the meter is closer to the lens than on the screen used type. That ebay button is not correct either and may be taller than the correct alcoswitch indicator. For a screen accurate red rectangular indicator you need to order one of each of these:

Lens:

Housing:

Bulb:

(T1 3/4 Flange base, can also use red LED bulb with flange base instead)

You should be able to completely reassemble the meter without the indicator hitting the glass.
