This Model 4 is a custom large bore symphonic tenor trombone made by Manfred Schmelzer in Germany.  Manfred has passed away in January 2026 so this is the last one.  A lightweight instrument with an axial rotor like this is captivating, and the bell kranz keeps the tone in check.  It's especially resonant and fast. 

Besides the nickel garland on the bell (kranz), this has a reverse F slide to add more mass to the slide and its connection to the horn.  The minimal bracing allows the bell to fully vibrate.  The grip for the hand is not overly large and the trigger throw is normal for for this design.  The bell is ornately engraved, suiting its German heritage.  The hand slide end crook is slightly straighter through the middle than US designs.  The tuning slide and F slide have the same very round radius.  This shape puts a little more length of the instrument within the tuning slide rather than in the neckpipe, so it plays more open, a little larger, faster.

There's always a story when you get a Schmelzer.  I contend that no two are the same.  I'm sure there aren't many Model IV like this, if any.  Schmelzer is retiring so I decided to buy a group of trombones from his last production run.  I was fairly sure some of these are from his trade show display, and this model IV is part of that.  I could see if from the FB posts.  Upon arrival it didn't play at all, so if you had tried it at a trade show and wondered, yes the rotor was misaligned.  The hand slide was also rubbish so it went with other slides to the master Bruce Belo for a tune and clean.  Now it'll work well.  The bell went to Charles Hargett at Brass Mavens for an alignment and cleaning, removal of some dents and marks from use.  Where are these components from?  Manfred fabricates many parts including bells and leadpipes, but the F-attachments and slides of his larger trombones bear a strong resemblance to Arnold Stoelzel and Rath R-Hundred trombones.  I suspect the parts kits are the same.  Some European, some Asian, it works.  Now it plays and I can represent it. 

This is a light and very open horn.  Down low you can blow it like a bass trombone, but beware it'll zap your air.  Compared to an Adams Sonic today, the Schmelzer is more open, has a broader tone, but is softer, more malleable, less stable.  So I experimented...and a Kanstul BB leadpipe (Byron's Bach) fits well and gives back the resistance I like to control things.  That's the setup for me, and the Schmelzer will include this leadpipe along with the original.

Now the Schmelzer axial feels nearly as efficient and centered as a rotary trombone, but big the way axial players like it.  It makes this a terrific playing horn, one I want to keep.

Ehh. Not for me.
Color: Gray
Foot slides when walking in them. The fit was tighter than lead to believe. It did hold the moisture in but the silicone patch is small

My feet feel softer and smoother, and I love that I can wake up to beautifully moisturized skin. Comfortable Fit: The socks are incredibly comfortable to wear, with a snug yet gentle fit. I appreciate that they don’t feel restrictive, allowing me to walk around my home while wearing them without any discomfort. They are also lightweight, making them easy to slip on before bed. User-Friendly: They are super easy to use—just wear them overnight, and let the socks do their magic. I love the simplicity of incorporating them into my nighttime routine. Durable Quality: The quality of the socks is impressive. They wash well and have maintained their shape and effectiveness after multiple uses. I feel confident that they will last a long time.

These worked for me!
Color: Original Grey
They worked great. I bought these for cracked sore heels. It took 2-3 weeks but my heels no longer hurt and the cracks have closed and look more like an indention than a crack now. They feel so much better, but I'll probably wear them another week just to be sure they stay healed. They look and feel like regular socks from the outside but only cover the heel with the toe open. Not think but not thick, again like regular socks. They would probably be slippery on a smooth surface the same as socks. The inside feels like rubber or something smooth at the heel. I have washed them once each pair and accidentally dried one pair in the dryer. They still seem to feel the same so I think they're fine. They're pretty inexpensive and had different colors and sizes.

Truly Helped My Cracked Heels
Color: Original Grey
I didn't include a photo cause they look exactly like their advertisement photo. I so liked the silicon-type heel lining as it kept the heel-repair cream on my heel and did not get soaked up by the sock. But, it is so, so slippery when walking around in them! Take care to be mindful when you set each foot down as the lotion can slide your heel across the sock quite a bit. If these socks were for an elderly person, I would have them only sit while using the sock - no walking around for fear of falling. I have larger ankles and found that having both the top and the bottom hems/elastic, etc. the same size to be quite troublesome and was not a nice feeling or fit on my upper hem that hit my ankle. Don't get me wrong, I am so glad that I got them and I continue to use them and they are helping my horribly-cracked heels greatly, but I find that I have to keep moving the top hem up and down so that it doesn't stay in one position as it cuts in to my ankle. My feedback and advice might be to please make the upper hem somewhat larger than the one that is on the bottom and goes over my actual foot. They really should not be the same circumference...or else make different sizes - S, M, L, etc. That's really my only complaint or "con" to ordering these. I think they are a great concept and I like the fact that I can throw them in the washer and dryer.
