STUNNING FREE ROLLING STERLING SIREN FIRE ALARM CO FIRE ENGINE MODEL 20 6 VOLT.  I am not an expert on these, but I do know that the Model 20 is one of the most desirable, and certainly the best looking of all of them.  This unit has not been tested.  It will be sold in as-is condition.  It was stored in an old shop for many years.  I can see a few twigs and such behind the grill.  It will need some interior cleaning/detailing.  I have NOT opened this up.  No point since I don't know what I am doing.  Very little to no rust.  I count a total of 4 of the tiniest dings, all on the cone.  I have taken a few pics of them, you might be able to see them if you look closely.  Superior unrestored condition.  I honestly don't think you can find a much nicer one!  Email with any questions and I will try my best to answer.  Approximately 13" long, with a grill that measures approximately 6" across.  This item is VERY HEAVY.  Shipping will be much higher than I am charging.  International shipping through the eBay International Shipping Program ONLY.  Thanks for looking!
