Which AC compressor is this?

[redstack]

Just curious, is this the stock 84 ROW compressor or an aftermarket one? Can anyone help me with an ID?

I loaded in "84 Porsche 911 engine" into Google.

Yours looks like a lot of them. Suspect stock.

Click on images in Google.

That is a stock nippondenso 10P15C, with R134a charge port adapters.

Thanks Kuehl, I had hoped that it was an indication that someone had upgraded the AC on the car some time. Spending some time on your site, getting informed.
