R-507B doesn't exist, at least last I checked... 
Did you mean R-407B? It has been quite some time since I've seen it.

Did you mean 507 A never heard of 507 B.?

R-507b ?
At minus 70F I believe you mean R-508B, and that refrigerant is also know as SUVA 95 and can be purchased at any refrigerant wholesaler selling DuPont refrigerant. P/T charts are also in the ASHRAE Fundamental Handbook.

i stand corrected it was r508b and i did find the temp chart for it

I need to buy a small amount of r508b for 1 job and don't want to invest in hundreds of $ m for more than I will never use. any suggestions?

Sell the customer the jug depending on your area it can take a day or two to get so they will always have it on hand. If it’s a good customer sell it to them a little over cost that way you don’t have dead inventory . If it’s a bag customer tell them to call someone else.
Honeywell you can buy better but you cant pay

Don’t think that’s going to happen unless he has r23 or something older and more expensive
