Can someone help me identify my DIN First Stage Regulator?

[99whiskey]

I purchased this regulator several years ago but cannot now identify brand or model. I would appreciate any help. I find no distinguishing marking except the serial #.
Thanks in advance,
TIm

That is an Aqualung/Spiro first stage. It was sold under various names, but it’s often recognized as the AquaLung Cousteau/Sea first stage. It was sold with various second stages.
