AGAdiver, Akimbo contacted me about your enquiry. I am in the process of finishing up a change in address and have not been able to follow SB as closely as I had hoped.
I do have 2 full sets of cylinders in storage for the time being. I can obtain detailed close pictures if you will describe your image requirements as the 1st step. Likely in the next few days or so.
I have the necessary scale to obtain fairly accurate shipping weights, but I have no idea of the shipping regulations on dive cylinders. If you will obtain the shipping requirements, we can go from there.
They are the threaded variety, no O rings. If you will attend to obtaining shipping regulations, we can go on from there.
FYI...One of the sets does have a cracked "coupling" manifold. I speak of the resin (plastic) unit that binds them NOT in the gas system.
Just let me know. I am finishing up my move, so my reply may not be a quick turnaround.
