Since I made it through this past semester with both sanity and GPA intact, I decided I'd earned a little something shiny. I found a Holton Revelation on eBay in very good condition, and decided to buy it. However, despite pouring hours of time into researching this thing, I can't seem to find out exactly what model it is! ( I apologize in advance for the lack of pictures, I'll try and snap a few and upload them as soon as I find a spot with good lighting) Here's what I know for sure about the horn: It is lacquered (mostly), with nickel trim on the valve casings. On the bell, there is an engraving identifying the horn as a Revelation, then signed by Frank Holton. According to the eBay listing, this was rare, though based on my own research, it's a standard Holton Engraving. The serial number reads 117xxx, dating it to 1935. (Holton Loyalist.com - Serial Numbers) The mouthpiece receiver does not seem to fit the Bach 6C that came in the case. The mouthpiece goes in, and will allow me to play, but there is a wobble and the mouthpiece falls out easily. However, the 6C looks like it may be a very old mouthpiece, and I have not had a chance to test a more modern one. The bracing seems very nonstandard compared to pretty much every other trumpet I've seen. There is no brace in the crook of the main tuning slide, but there is an adjustable slide lock between the tuning slide and the bell. There is also an oddly-shaped brace on the leadpipe. Rather than the standard slanted strut, it looks like ")(". Armed with this info, I took to http://www.trumpet-history.com/Holton Models.pdf and checked to see if any of these models matched the characteristics of my horn. Based on the date I found earlier, and the lacquer and engravings, I can make guess that the horn is a "Holton Revelation New Professional Trumpet (Third Generation)". However, the bracing does not match at all, and my horn does NOT have an underslung 3rd valve ring like the professional. Could this have been a Professional that has been modified or custom built? I don't see any obvious solder marks or damage to the lacquer near the braces, so if the horn was modified, it was relacquered afterwards, probably. Anyway, I'll stop rambling and let you guys think it over. After all, mysteries tend to be pretty fun!
