FYI, I ordered a brand new Hornby Black 5 from this trader on pre-order. When it arrived it came with a tender which had the old style pin connector and early crest whilst the loco had the correct plug connector fitment.
This actually rendered the loco inoperative. I contacted the owner who was dismissive and basically accused me of swapping the tenders over. Why on earth would I do that when the electrical contacts are not compatable ?
Numerous telephone calls were made to the shop, where his partner claimed he was not in the shop. I could clearly hear his voice in the background.
He later admitted he'd never checked the content of the box prior to despatch.
After a few weeks he reluctantly sent a replacement loco out with no apology.
Sorry if you don't agree, but that in my opinion is poor customer service.
Rather than clog up this blog, may I suggest you PM me if you wish to discuss this further.
