Where to download USG100 legacy firmware

I have a remote office where the USG100 has failed.  There is a USG100 kept as a spare but has never been upgraded.  When I try to load the latest firmware onto the spare it is not compatible.   I have read that I need to first install a later version of version 2.2.0 ( C6??) but the old firmware is no longer available for download.  Where can I find it?

    i recovered an old usg 100 from the basement... with a very old 2.20 fw. 
    I would like to upgrade to 3.30 AQQ7 but it fails with "not compatible". Also AQQ6 and AQQ5 give same result.  I suppose an intermediate release is needed. Someone can send it to me?

    The product's model id is 1500
    The ZLD-current image support the following product model id:

    Firmware product model ids are all not compatible to this product

    Thanks in advance
