Looking for info on these 2 vintage cues

[3cfan]

Can anyone shed some light on these two vintage cues?
Any thoughts or info appreciated.

Helmstetter cue with original and Kilby shaft.
What is Ap/6?
Is '1 of 1' actually a 1 of 1 cue?
Age?
Value?

Brunswick cue with original shaft.
Unusual cue as the forearm is square and lots of inlay.
Is this a 1 of 1 cue?
Age?
Value?

Thanks for the info.
The carom shaft was made by Kilby, the other shaft is original and tapered for pool.

That odd. Every ADAM/Helm with wood-screw joint i've ever seen was made for caroms. Orig. shaft may have been re-tapered for pool. Cool cues. ADAM made nice stuff.
