Dacor Aero Pacer

I have recently acquired by gift a used Dacor Aero Pacer first and
second stage reg. I can't find any information about this product. I
assume it was a relatively low end product. I wouldn't use it for
anything technical or extreme. I want to use it as a backup and/or as a
pony reg. I know it was well cared for (I knew the previous owner well),
but I don't know if I'll be able to get parts for servicing, etc. Does
anyone know anything about this reg?

TIA.
