The clue is in the word "style". This is an indication that it is not a real Sanden unit but rather a china made clone with lesser quality at a lower cost. If you cruise the internet you will find many sanden style compressors for sale but few real ones.
Just an update on my ac system: I finished the installation over a month ago and it is working fantastic. So happy that the brass adapter fittings from flared end to o ring fittings along with copper crush washers allowed me to keep the original evaporator in the dash after flushing it completely. Everything else was replaced with new. The sight glass in the dryer tells me the system is holding pressure and apparently not leaking. I drove the car yesterday in 100 degree SoCal heat and the engine temp was around 195 and I only needed the ac fan on the lowest on the two speeds to keep me cool. Finally have ac after 30 years of being the caretaker of my dads car.
Congratulations on a job well done. May it serve you flawlessly for many years to come.

Awesome. I have that on my list of TO DOs right now, and debating whether or not to go R134 or not. Been trying to educate myself and read all the posts and tech articles about which way to go. All my hoses etc look good, have all the parts, but I think I'd want to get a new dryer and condenser regardless. I may be hitting you up for some tips...
