@Training Wheels posted:To make this even more suspect, the seller's items have the number boards from these two Premier locos. According to MTH's product locator, those number boards (5521 & 5524) don't appear to have been issued on any RK engines.
I think I found them in a round about way.
30-2184-0 https://www.mthtrains.com/30-2184-0
These are not even protosound. Just horn and bell. You can't ID the road numbers on the MTH Website, but when you google 30-2184-0 there is a worthpoint web site show shows a picture of those two engines with numbers 5521 and 5524.
Back in the day, $159 for the pair brand new.
