RIVAROSSI STEAM " SCREW SIZES"?

I HAVE A COUPLE RIVAROSSI ENGINES 2-8-0 AND 0-8-0’S AND NEED TO LOCATE THE SCREW SIZES THAT ARE USED TO ASSEMBLE THE ENGINE, HOPEFULLY SOMEONE HAS A PARTS LIST NAMING ALL THE SCREW SIZES AS I WILL JUST GET THEM ALL SO I HAVE EXTRAS ON HAND, ANY HELP WILL GREATLY BE APPRECIATED. THANKS!!!

None of the Rivarossi models I have show screw sizes on their exploded drawings, but they are no doubt all metric. Your only hope might be to contact Golf Manor Hobbies. I have never dealt with them, but have read several messages here in the past indicating that they stock Rivarossi parts. They may even have a screw assortment for each particular model.
