Texraid, I'm leaning that way as well, but don't really know what would be appropriate, I assume american made at that point in time, would that mean Lyman? Leupold?
Mike, The Rigby has no holes, and I won't be the guy to add them. The Westley Richards appears to me to have been built for a scope, notice the shape of the stock & bolt, WR cannot confirm/deny that the mounts are factory though.
Michael, The current bases measure 19 mm, I'm thinking of using Warn or Talley QD's for a BRNO/CZ until I find something more appropriate.
Vall, I'd like to do it right, I'll spend some time & effort researching.
mkbenson, Here are a couple of pics.


Thank you all for your input.
