I don't see a link or picture???
Why though, out of all the engines, would you pick Murdoch to add a front coupling to? If anything I'd think Arthur, Percy, and Mavis in that photo would be the prime choices!
maybe the person was doing experiments before moving to more expensive and rare engines. i tried to do one on Thomas (since I have a million of them). Sadly I didn't have the tool to do it. The plastic is too stiff
Yes...Emily, Molly, Mighty Mac, Original Hank, Harvey, & Plarail Rocket, along with the 2nd generation Plarail talking Thomas & Percy, and the Original Steam Thomas' are all tender driven, though The Steam Thomas runs great compared to any of the others.
Play nice & have fun!!
