I may as well move this on - it's a top normal long cage version and 9 speed but will happily work with 7/8 as well. It was bought with a view to try out a bit of Shimano on the cargo bikes at work but I stuck with SRAM in the end.
The mech has only had a chain passed through and so is unridden and as new. It does seem to have picked up some scratching on the back of the cage (?) but this isn't visible once all is fitted and running
These seem to be around £35-40 to buy new at the moment so I was thinking £25 posted. Payment can be by Paypal or bank transfer, etc. Pictures below...
