Conn Jazz Trombone Identity

Hello,
I have a silver plated Conn jazz trombone. Played in HS '95 and '96. From the serial number 41-347915 it appears to have been made in 1991. I'm unable to figure out the model number of this instrument. The bell measures just under 8" (7-7/8"), is engraved in cursive with "C G Conn Ltd" and there's a 483 stamp on the slide piece. Ultimately, I'd like to sell this instrument because it hasn't been played and it should have a proper home. Before I sell it, I'd like to know the model number and approximate value. Slide is in fantastic shape too. Any help is appreciated.
Thank you

Yes, that serial # would suggest 1991. A photo or two would help us identify it. One overall shot and one of the bell engraving? Also, Conn model numbers are usually stamped on the slide or bell section (or both) near the slide tenon/receiver somewhere.

Looking through the FAQ's it appears I need admin approval to post an image...is that accurate?

I'm not sure about that, but if you can put an image somewhere else, you can post a link to it.
There should be a two digit number and a letter stamped near where the slide and bell go together, on one or both parts.

Did you try? You should be able to attach files at the bottom of the post editor.

The bracework on the tuning slide area indicates a 100H. This is a pro level horn that replaced the 6H.
However, a 100H would have a curved brace under the mouthpiece and this one appears to be straight.
It's entirely possible this is a 100H bell coupled to a different slide. A lot of different Conn slides would fit.

Possibly the 100HSP?

A lot of 100h have straight brace on slide. That picture is a later 100h. It's not sterling, it's silver plate.

That makes sense - thank you for the info.

Thank you all so much for your assistance. For my next steps, selling this trombone, what are your recommendations for reaching my target audience? Who would be most interested and how would I reach them? Is this site a good place and/or are there better markets besides ebay and my local instrument re-use boxed stores?

Here, Reverb, eBay. You could also consign it at a place like Dillons, Brass Ark, Brass Exchange.
100h can go either way, some people love them, most people are kind of indifferent. People might want to play it before buying it. So if it's a good one, try to sell it locally. If it's not a good one, sell it on eBay. They range in selling price, maybe $500-1000, depending on condition. Yours looks pretty good. Usually the silver plated ones are said to be better, although I don't think there's any real confirmation of that. Also, some buyers might be looking for that curved grip. So yours has pluses and minuses.

Can anyone explain why the 100h is not as sought after as its predecessor the 6h?

From the lore, they are famously inconsistent. Some are amazing, some are dogs. Any one you buy sight unseen is a 50% shot at being a good horn, and there are plenty of other safer bets out there for the price (like a 6H).

A lot of them were dogs. That is not true of 6H's at all.

Finally getting around to listing this piece. How do I know if it's a "dog"? It sounded amazing when I played it in HS...not sure if that's a good enough litmus test or if I should take it somewhere locally and try and get it rated if that's a thing.

Where do you live?...
You might be able to find a local trombonist who would be interested in playing it - just to check it out. And, if a good play, you might have a buyer too. 100H's aren't rare but we don't see them everyday.
