I suggest that you remove the mainspring from the barrel, then measure it - length, width, and strength. Also note the type of ends.
If you PM me, I'll send you a chart with mainsprings listed with all the dimensions.
As for where to find them, I frequently buy on eBay, but there are other sources such as Ofrei, Esslinger, Cas-Ker, watchpartsrus, etc. I prefer new white allow mainsprings to the old stock blue springs.
Good luck
Doug
