Vista 510 TapeRecorder made in Japan by Craig-Panaorama, Ser. V-4-58986, with a Dynamic mic NDM-26. 
This item was power tested using 4 D size batteries (Not Included) as the external ac power adaptor source is missing. 
The battery compartment has some dust and dirt from storage. There is a small area where the Dynamic mic is stored next to the battery compartment. The mic did not make noise over the speaker, but would stop and start the tape with it's side switch. 
The tape was found with the recorder and it's age is unknown. The recorder will play, rewind, and work when Record is on, but due to speaker not making any sound the recording function is also unknown. 
There is a manual guide inside the case. The Radio and Ear inputs were Not Tested. 
The exterior case is a grey color, has some stains/dirt marks from age and storage. There are rubber feet on bottom and one side. The clasps are on 2 sides. The handle will pull up for carrying and then lay flat along one side. 
See all the photos for more details and condition & the video for short test of recorder. Due to age, speaker issue and limited testing with aged tape, this Vista 510 Taperecorder is Selling As Is, No Returns.  Case is approx. 12" x 9.5" x 5" and about 8 pounds.
