    Help to identify devices by photos

    Hello, friends. Could you help me identify these devices? They present in The Big Bang Theory TV show. I have already checked fan websites. They didn't help. I was able to find photos, but have no clue what they are for. Please tell me the purpose of the device. If you could tell me exact name and model It would be awesome. Sorry for the small size of some pictures, but it is the best I could find.

    Re: Help to identify devices by photos

    Hello,

    the device in the first picture looks like an old VTM. I think it is DIY.

    The devives in picture 2 and 3 looks also DIY, because I can not see any logo .

    Device no. 4 is especially made for weatherforecast. Here in Germany it was built by Lambrecht GmbH. https://de.wikipedia.org/wiki/Thermo...mbrecht_hg.jpg since 1980

    Pictures No. 7 and 13 showsan Intercom between offices. E.g. Between secretary and director or other offices.

    Picture 9 looks like an TV camera for observation

    Picture 11 looks only like decoration. The "big bottle" on the right side can be a CTR for oscilloscop.

    All other devices i can not indentify.

    I hope it will help you.

    best regards

    Rainer
    PS: Sorry, if my English is not good.

    With respect to photo #4:

    Here in the US there was a company which specialized in paper chart recorders: Leeds & Northrup.
