3 inches. I bought this 15+ years ago. Never played with or displayed. Just stored it away. Time to get rid of some stuff! Great condition! Non-smoking home. I CANNOT ACCEPT "BEST OFFERS" or respond to messages asking me to take less. Thanks so much for your consideration! Just trying to clean out my closets and some family stuff. EVERY order ships on time...please note my handling time BEFORE purchase. Shipping cost covers packing supplies and a drive to the post office. With that in mind, ask me about combined shipping or partial shipping refunds for multiple items.
