Wrong pic.. Can't screenshot of this old desktop, Your 4th pic of the blue sticker,, same location on the ebay one. Swear it says CW20 if you look close.... https://i.ebayimg.com/images/g/k7YAAOSwTM5Y5UuH/s-l1600.jpg
Ok, I see what you are getting at.
It looks like that lable is on the handle. Mine is worn off.
So the handle P/N is CW10A and the cutting end is CW20.
Now I just need to figure out the part numbers for welding tips and search ebay for those

On their website the PDF Catalog,, CW20=== Would be C=series, W=Twin hose, 20=tip size. Goggle search "size 20 torch tip" and see what you get.
Stopped by two different welding shops today. Both where stumped and had no clue as to what the torch was that I brought in. Said they never heard of the brand.
One had some Victor cutting tips that looked to have the same profile or shape but where larger in diameter. None had any clue as to welding tips that would fit my handle
I may end up, as much as I don't want to, just getting another brand torch handle and tips.
I also dropped of the tanks for hydro testing. Next stop, find a place to fill one with nitrous oxide. Any good recommendations on the Sacramento area?

Ok
Ya took a while to get back to this.
I worked for Praxair for 18 years but please don't take this as I have a clue. lol
Yes Nitrous is filled with liquid by weight. Which means that size for size a bottle of nitrous should last longer than a bottle of oxygen which is filled by pressure volume, just gas pressure.
That being said as the nitrous pressure drops the liquid will actually convert to gas replacing the pressure in the bottle were as oxygen will just drop pressure till its empty.
As this sounds good it all depends on the application. Yes nitrous will replace its pressure but it is a slow process and it dependent on the temp of the bottle and if your using it at a high volume it will not replace it fast enough and as soon as it drops below a certain pressure (don't recall off the top of my head) the liquid will turn to dry ice and is basically worthless and this is even more likely if its being used in cold climates. Now it will convert back to liquid but it takes heat and pressure and it takes a while.
As you now know its also very expensive to use.
Nitrous at 70 deg bottle temp should range close to 760 psi. And should avrg 10 psi per deg increase.
Couple diff options they used to sell for cutting is propylene and starflame c both are better propane alternatives.
As far as adapters you just need to look up the proper cga connections and should be able to purchase anything you need.

Thanks Bagged,
I am quite familiar with what you stated, having training in air conditioning. Boiling points, latent heat, sensible heat, vapor pressure, etc.
The heat of vaporization for NO2 is only a little bit more then propane and we know how propane will get cold or freeze over if too much is drawn out too quickly. With that, I don't believe I will pull the gas that quickly, especially with a torch set. But will not know until I give it a try
As for propylene and similar fuels, they would sure be nice. Problem is, I can't get them unless I take a 20-30 minute drive to my local welding shop. They already refused to fill my current cylinders due to "company policy" so I am looking for easier ways to maintain a light weight but capable torch set up.
Propane can be filled at many gas stations and big box stores around me. NO2 is a bit further away and cost a lot but if it works out (I have my doubts) then it will be worth it. Otherwise I search around for one of those oxygen concentrators and compressor set ups for home filling medical cylinders. Then I can fill the oxygen at home and fuel locally for cheap.
Cutting is low priority, or gets little use. I mainly need it for heating and brazing so gas draw will be slower so hopefully keeping pressures reasonable

It's alive!
Not really suitable for cutting but that is the only torch tip I currently have. I think the excess nitrogen in the NO2 make it blow out when you press the lever.
It does seem like it would work excellent for brazing and heating which is what I built it for.
Interestingly the flame has a violet hew to it.
