There is a few back issues of CTT and Model Railroader that I want to complete my collection. For a long time on eBay I go Toys and Hobbies, O Scale, Magazines. There are usually around 82 pages. I would scroll quickly about 21 pages were all I could stand. It’s work. At the risk of competion and this may be obvious to many but I didn’t think of it. I now search CTT and year. Model Railroader and year. This gets results from all the pages, many of which I skipped before. At the bottum of the page you also get results from all catagories. Those I certainly missed out on before. There is a Greenberg book out of print. Lionel Trains 87-95 that so far is more than I want to pay but there is much better chance of finding it now.
