Big thanks to Paul Chetter, a parcel arrived this morning with a Zimo sound chip and a selection of speakers to try to see which sounds best in the Hymek. Liking the look of the big round one to go under the fan 🙂

Also cab roofs are getting there, vents are in place, just need the airhorns then I can get them painted

EDIT: Cab roofs fitted out and painted, couldn't resist adding the pipework to the horns ....
