Headford Disc Diffuser Bubbler

[Snappo]

I'm interested in buying just one of the following:

• Headford Layback Jacuzzi Disc Diffuser Bubbler
• Headford Glass Worked Jacuzzi Layback Bubbler with REVERSAL Disc Diffuser and Matching Ice Pinch Slide 14mm # H2
• Headford SLYME Jacuzzi Bubbler with Disc Diffuser and Matching Disk Diffuser Slide 14mm

The top of the 14mm female down stem must be taller than the glass bubble next to it, as I will be using it with my Lotus vape which needs the extra clearance. The following vid shows what I mean:
