Some excellent posts up above bringing back happy memories of those hazy, halcyon days.
Steviebee........I remember getting my dad to drive me to a gunshop out of town when I was about 14 or 15 and buying some of the Lane's Heavyweight Special whilst there. Pretty sure they'll be the ones you mention and were truthfully and woefully awful in consistency of dimensions.
Thinking back, I think I bought my silicone cloth (maybe a Garcia one?) at the same time. I still use that cloth to this day with a tiny drop of Abbey 35.
