Please see all pictures and use zoom feature.  Often the pictures describe the item better than words.!
Also please see the other 2500 vintage radio related parts I listed.   I always combine shipping to my best,  just order and wait to get the invoice from me.  On Global Shipping I cannot combine as that is in Ebay's hands.
