[Trombone-l] Repairman in Helsinki?

[George Butler]

Tere, Y'all, (that's Estonian for "Hello," and north Louisiana for "Yous guys.")
 
Can anyone recommend a repairman or slide specialist in Helsinki?
 
A couple of days ago, I dropped a sackbut slide--not just the outter, but the inner and outter together--from a height of ten feet.  No visible damage, but it is obviously "torqued."
 
Fortunately, the horn in question was not my Egger!  :-)
 
Come to think of it, that slide trumpet that I made (well, actually that Barclay, Serephinoff, and Munkwitz made) last summer could use some "final tweeking" as well.
 
Many thanks in advance!
