Just to add one more piece to the snap cap puzzle. According to the gentleman I recently bought my Scamp
13 from, he got the last of the small size snap caps that Scamp
had. When he asked them what folks should use, the guy at Scamp
told him just to use a large size, secured with a dab of sealant.
I guess my point is, if you have missing snap caps, at least the small ones, you will have to replace with larger size, or just use the sealant to secure them. Unless you have an alternate supplier of the small size of Snap Caps. Scamp didn't think it was a problem.
At least that was the information I was given by the PO of my Scamp, he had just dealt with the issue when he replaced the caps this past fall
