Hi Harry
'-------------------------------/ I'm considering doing a run of boilers for the Denver and wondered how well received adding a water gauge would be. '-------------------------------/ Sounds great to me. A sight-glass type, right? '-------------------------------/ I'm open to other suggestions for other additions/improvements. '-------------------------------/ Okay, I have two. I know I'm dreaming, but being able to coal-fire it would be a kick. When I was looking at Cheddar boilers, a nice little fuel tank caught my eye. A tank would make a nice addition to your boiler. James James Counihan Seattle
