These are good used parts. The leadpipe and bell on this horn are a little rough, but could still be used. Slides and braces are all in great shape. The horn's serial number is not printed on the finger paddle bracket. The bracket has evidently been replaced at some point. This is certainly an Abeline horn - likely an early one based on the finger paddles and a few other signs (such as the early style engraving on the bell).
