Just to point out that your comparison doesn’t work.
O-ring / Loose ring is the type of cheek pieces and determine the type snaffle bit it is : Loose ring, D-Bit, Eggbutt, fulmer, Full cheek, half cheek, Baucher, Kimberwick, pelham, Dutch gag/continental/pessoa/3-ring, bevel,wilson, etc.)
Dr Bristol is a type of mouthpiece. This particular mouthpiece could be found in different snaffle bit : D-bit Dr. Bristol, Loose ring Dr Bristol, Full Cheek Dr Bristol.
Other type of mouthpieces : single jointed, double jointed (french link (or lozenge, or berry), Dr Bristol, etc), mullen mouth, segunda, double snaffle, waterford, wings, etc.
Then you have the shape of the mouthpiece: ported, slow/twisted/wire, ergonomic, etc…
And then you can add some extras: copper inlays, barrels, rollers, different types of joints (like revolvers, locking)…
Finally, they come in different material: hard rubber, soft rubber, happy mouth, sweet iron, argentan, aurigan, sensogan, stainless, never rust (brass), cyprium, salox, other different copper alloys, etc…[/QUOTE]
While you are absolutely correct, most Dr. Bristol’s I see come with an eggbut cheekpiece. Also, the reason I specified Dr Bristol as opposed to just an eggbut is that the cheek pieces on each tend to be slightly different (Dr Bristols [I]tend[I] to have slightly more of an oval shaped ring while most eggbuts I see have a more circular shaped ring.

I do understand that there are different shapes in eggbuts (and that they are both technically eggbuts) but if someone just does a quick google image search the first picture that pulls up when you search each is pretty typical of the norm for them. But again, you are absolutely correct, just pointing out why I labeled it the way I did. I have since gone back and added in eggbut to the description.
