{second post - obviously fumble-fingered the last one..}
I've recently bought some secondhand ZTC control kit (from OLivia's Trains, who I'd recommend). Unfortunately, like a lot of secondhand stuff, it came without manuals, which makes life harder. If anyone on-group has either surplus ZTC manuals (primarily for 511,
622, 521 and 304T, but also maybe for 550, 300(?) - their capacity discharge unit and whatever thair point control decoder was numbered as - can't read it on the item!), either in dead-tree or electronic form and is willing to share them then I'd be very keen to hear. All assistance welcomed..Thanks in advance, etc..
