Collectable, Rare Old ! As a guy going on 61 (now 63) that had his first train set about 1957. I have trouble with these three words in HO gauge. Ok ! At 61 I'll give you OLD . With the other two I have issues. I have some older stuff. Aquired thro the years. Things that were new when I was little. Some of them have weathered time better than others. These few may be refered to by these two words. Most can't. I don't understand why Revell Ho who's SW7 did not have the best of drive mechanisums but did have excelent product information on it ( the name and dateing on the bottom of the drive trucks ), Doesn't sell for more. The date 1957 on anything else would effect it's value. On a Revell SW7 it is still a out of scale bad running locomotive that only has value in good condition in it's box. Then people can collect it and put it on a shelf, never to run again or at all. HO now with all these new highly detailed, expensive models has changed HO, for now. For me finding a old Silvine 0-4-0t complete with nothing broken is good enough. Refinishing is a labor of love. I'd never redo it in a original paint skeam. Especially since I am not a B&O modler. Now CNJ or Reading has a place in my heart. Old Names like Gilbert, John English, Bowser, Mantua, Silvine, TrainMiniture, Penn-Line, Hobbyline, Roundhouse, Varney, Lindsy, Ken Kidder, American Train & Track, TYCO, Revell, MarX, Aristo-Craft, All have places on my layout.
