A short time ago I discovered in a tractor magazine an article about fabricating an Iron Horse silencer from steel plate, it gave the dimensions & instructions, over 2 pages. I can’t now find that particular magazine, it could have been ‘Cultivator’, ‘Farm & Horticultural Equipment Collector’, ‘Vaporising’, ‘Old Glory’, or any one of the other similar magazines. I have over 300 various mags…but don’t want to spend rest of my life searching them all! CAN ANYONE TELL ME WHERE TO FIND THAT ARTICLE? HELP!!!
