Thanks Craig, I had a feeling you would know what it was. I was guessing Adam's, but I was guessing.
It looks like maple under the wrap.
To answer Tommies question and for your information these cues were made full spliced, the cues forearm was spliced to the handle in a similar fashion to what Burton Spain used. I have refinished a couple of those cues for customers, and they are well worth bringing back to life, here are pictures of another one of these cues with the wrap removed.
The first two photo's below show the type of splice used by Adam in your cue, both cues pictured are full splice although the splicing technique is different.
The photo below are examples of the splicing technique used by Paradise and Palmer.
The photo below is the technique use by John Davis, and John worked with Burton Spain in the Late 60's and then bought Burtons business in the early 70's. Later Burton purchased the business back from John and continued to build cues cues until his death in the early 1990's, before his death he sold his operation to Joel Hercek and for approximately a year he trained Joel. Later John Davis also starting building cues again, and in the last few years he has also started selling blanks again.
This full splice technique was used by many cue makers who invented the technique is unclear and most likely will never be known, however, one thing is clear Burton Spain and Richard Helmstetter were very good freinds and Burton sold Adam cues through his business. Whether one of these gentleman sold blanks to Palmer and Paradise is anyones guess.
Have a great day hope this helps.
