My EFE Hymek arrived with one of the headcodes snapped in half, and no plastic glass over the headcode. Nothing in the box, so my assumption is it left the factory like that. I must contact the vendor to see if they can help replace the ‘glass’ at least.
I fitted Ultrascale replacement wheel sets to my old Heljan 7036 today, gave the geartrain an oil, and it runs perfectly (had been in its box for several years due to the original wheels - and how often they needed cleaning). The wheels took about three months from ordering to delivery in NZ, but they are well worth the wait IMO.
