You are getting all 5 as a package deal.  I am not going nuts answering a million questions on these.  I'm well aware some are worth $100 each if not better.  I have supplied detailed photos and a no brainer price.  

         Just one is worth it alone.  I'm also stating as is.  They may or may not work.  These have been in dry storage over 40 years.  If anybody is awake out there you just hit a home run.  I don't want to know bout them.  Being sold as is cheap final sale.
