Nice find on that frame 1918, my best guess is the buoy was made by Flotation Tech, it doesn't make sense to outsource that.
I think MSI makes surface buoys, surface being the key word.
From the looks of the weights and cable on camera, it leads me to think that buoy will be tethered under water and be connected to the mudsled.
just imo

This is from the Marine Reporter in 05
"Mooring Systems
supplies instrument frames and surface buoys to a large
number of instrumentation manufacturers on an OEM
basis."

Looks like Mooring Syst. Inc and Flotation have a long time relationship.

Abstract
Describes investigations by Flotation Technologies and Mooring Systems Inc. to develop a low drag subsurface mooring apex buoy that contains an RD Instruments acoustic Doppler current profiler current meter.
Five different candidate mooring apex buoy systems are compared with regard to their drag, inclination and stability in current and effect on the performance of a typical mooring. The drag coefficients of cylindrical and spherical buoy candidates are Reynolds number sensitive in the velocity range of 1 to 3 knots. This leads to calculated and observed hydrodynamic instability due to minute variations in current velocity. An airship shaped streamlined body was found to have the lowest drag, best inclination response and little or no Reynolds number sensitivity in the current regime of interest

Then in 2005 Flotation Tech has this news release

"Flotation Technologies Develops New Low Drag ADCP Buoy"

OCEANS 2005, WASHINGTON DC — September 20th, 2005 — Flotation Technologies, Inc., a global leader in deepwater buoyancy systems, today announced a new ADCP deployment product. Specifically designed for high current applications, the Flotation Technologies StableMoor™ is designed to reduce drag and increase mooring stability in extreme flow regimes."
