I'm working on an estate and have about 25 horns to go through, many of which are obscure and less than common versions of standard instruments. I have here 3 of them (for now) that I'm having a difficult time figuring out what they are, and more importantly, what their value is, so that I can assist a widow in liquidating her late-husband's collection. Any help would be much appreciated here, so these are over my head! I have a few more that I will need help with, but this only let's me upload 11 pictures per post, so I'll update with the others if you guys are able to help me out. I appreciate anything you can do. Again, I'm looking for help valuing these, and further clarification.
Here's a Holton (Bass?) Trumpet serial # 400xxx - all slides and valves are clean and free moving, pretty sure original lacquer, amazing condition. Measure about 25" from end to end
Here's a Selmer "K-Modified" 24B serial 428xx. I have no clue what's on the side of it on the lead pipe...but the "cap" screws off to a small opening. Slides and valves are clean, valves are good, some sluggish slides, also great condition.
Here's a Getzen Tone Balanced Super Deluxe Trumpet (Herald?) serial # 86417. valves need oiled, one stuck slide, but overall amazing condition.
Here's a Conn (Bass?) Trumpet serial #K31xxx. All valves are good, slides are all moving, just a little stiff. Amazing condition. Measures 22 1/2" long.
