Wow! That's really very nice. I have seen a number of tenders on eBay- no doubt remainders of scrapped-out Hallmark engines. I bought a Hallmark from Peachtree- It had a gearhead motor! But, it ran maybe a hundred feet before it developed a lope. Then it just stopped dead. The spokes on the main drivers had crumbled. This seems to be very common on these models. I thought I might be able to put the superstructure on a Bachmann mechanism, but the HMK had been filled with lead an shot.
