Keros mantles - CP ratings?

I got a bunch of these Swedish mantles from Keros with a 350CP lamp, but I need some help understanding the CP rating.

The say «Nr. 900» and «200 nlj.». Do any of these numbers relate to the CP rating? They seem to be quite small, but I am not sure whether they are for 350 or 250 (or other) lamps. I appreciate any help with this!

I would say 200cp

 

Hi Håkon,

AB Keros Södertälje/Sweden, was from 1903 a subsidiary company to AB Lux, Lilla Essingen in Stockholm. They were probably the largest manufacturer and supplier of mantles in Scandinavia in early beginning of 1900.

Your mantles are for lamps of 200nlj, which means 200 "normaljus", a Swedish term similar to that of CP/HK.

Thanks for the detailed feedback, @Conny C ! I'll be using them with smaller lamps, then.
