I recently purchased a vintage Lamiglas SH1261L Blank. It is a 10'6" 2 piece Light action steelhead S-Glass Rod Blank with spigot ferrules. I plan on building it in a spinning rod configuration to be used with both a spinning reel and centerpin reel and used for large trout and small steelhead.

My questions are:

1. When were these blanks made?
2. What style of fishing were they built for?
3. What was the line rating and lure weight?
4. What is the recomended guide placement measurements?

Any information is appreciated. Thank you.
