Model 33 Teletypes acquired

Yesterday morning, I drove up into the mountains of West Virginia and got an ASR-33 and a KSR-33 with a few spare parts and a five inch stack of docs. I haven't had the time to do anything with them yet, probably won't get to play much until Christmas week. Anyway, the metal on both machines seems to be in good shape, but the plastic leaves something to be desired. The ASR is mostly just dirty, but there is a crack at the left rear screw position. The KSR is cleaner as it was used less, but it was stored improperly in a box and dropped or something and the plastic upper case (the gray case, not the white/yellow cover over the carriage) is broken into several pieces. So does anybody have recommendations as to glue or other solutions? Is someone sitting on a big stock of spare upper shells? Thanks, Bill
