This is just a fact finding thread as one of those things that is of interest to me and might be to others.
I have been collecting data here and there so the following maybe a little inaccurate so please feel free to add to it or correct it.
I often look at the cabinets and some are noticeably different and others similar but then wonder about the size of the playfields which then started the collecting of info.
