A while back I purchased a hydrocal kit from an estate sale. I recently got around to start to build the kit and

Hi, I have a problems seeing some pictures that have been posted. Some I see & some I don't. I don't know if its me or the site. Any suggestions?

I had built one for a friend. Take your time. The kit I built was the factory it came out so nice

to post some pics of it.
