1941 F.E. Olds & Son Super Trombone Vintage Low Reserve

This F.E. Olds & Sons Super Trombone was made in 1941, according to the serial number. Here's a link for dating F.E. Olds: /trumpet/oldserno.htm. All serial numbers on the horn match. There is no corrosion on the inside of the slide. I'm not sure if the mouthpiece is original to this trombone, but it does say Olds and Made in Los Angeles. The case is not original.
I'm not a trombone player, but I'll try and answer all questions. I have a photobucket album with more pictures of the trombone. Here is the link:
