DISCLAIMER: This page shows the pinball machine Collection of PinballOwners member gundogs from Denver, CO, USA. The coin operated pinball machines listed above, including their images, were uploaded into our database by gundogs himself; gundogs is the sole responsible for the information contained in this page. The pinball machines shown above are not necessarily for sale! Please refer to the 4th column in the list to know whether a certain pinball is for sale or not. Most likely gundogs's pinball machines are second-hand (used) pinballs that were once installed in bars and other public places; their value as a collectible largely depends on appearance and functionality of every single machine.
