Thanks for your help guys!

Think I'm going to try a HW35E first

Anything to look for?? I found this a couple of times:

"The fact the breach front face wears on the lever means if buying always ask for picks of this area, check under cylinder too as late ones (still now too I think) score up where cocking arm needs bending slightly, old ones especially single sided safety ones can have porous brazing so always chrono"

Anything else? I'll do a search and see if I can find out about changes over the years.... though please point me in the right direction if you know of any good links etc...
