Hi,
I took a closer look and the red piece for the pin is there so I am good. Glasses played a big part in that discovery lol.
I look forward to getting them back up and running again in the future, I hope to move in the next year or two but not enough room currently to set them up.
Another question, the socks have really suffered as my children grew up around them and you know how that goes. I was thinking when the time comes to have a seamstress make new ones with fabric I supply. Can you advise on what/where to choose?
Lastly, the original owner did not like the wood platform and replaced with thin acrylic sheet. It would always drive me mad as they appeared to tilt forward a little due to the acrylic being so flexible. I would like to get proper wood back, can you provide the dimensions I would need to have new ones made? I have searched for the years for any originals platforms being sold but never have seen them come up.
Any chance you live anywhere near N.E. Ohio 
Again, thank you very much for responding!!
