I've had some of the Lionel pieces in the 1700/2700 series buried in a box. A recent addition of the Ives caused me to dig them out. I'm a litho fan and these are quite colorful, although the detail in the litho is not as nice as earlier Ives. One could collect one of most all and not have too many cars.
Some random thoughts/questions.
I do not see a Lionel version of the stock car. Was there one and I have just overlooked it?
Sure wish the Ives versions had Ives couplers. I would like to pull them with my 1122 without altering anything. Guess I'll try a twist tie.
One of my 1717's has box couplers, one has latch? Shouldn't it be a 2717?
The covered 1717 came that way so I left it. Kind of a low rider caboose.
