I'm puzzled too, Chris. With numerals only 0.5mm/20 thou thick, anything more than a soft (plumbing or electrical) solder joint at their heads and feet would seem like overkill. The numerals seem to have serifs top and bottom, so if those are to be soldered into grooves, there should be an ample surface area of solder in the joints. If soft solder is good enough to hold copper water pipe together, it should be up to the job.
Also, there's less chance of (a) distorting the brass by localised heating and (b) getting it so hot that ends up annealed and can be bent too easily after it cools.

I would just use solder paste place them and put in oven for 5 min then turn of oven and let cool slow CUP alloys sell the solder past in both silver and soft I would use soft.

Pete, must admit I`ve never used solder paste but did think soft solder paste in the oven would be the way to go!
