T-28 Trojan & Instrument Catalogs

13 New T-28 Manuals, and 33 Instrument Catalogs Added This Week!

T-28 Trojan

All you T-28 fans out there will be excited for the manuals that have been added this week, and frankly I am too! I always have a soft spot in my heart for the Trojan, and the 13 new T-28 manuals from the Frederick Kohler collection are a great addition to the site. Some of them are repeats of manuals we already have, but they are originals rather than copies of copies, which I know we can all appreciate!!

B-25 Mitchell

Also this week, we've got a new B-25 Maintenance manual. This version has 826 pages and covers the B-25J, TB-25J, TB-25L, TB-25L-1, and TB-25N models of the Mitchell bomber. One of my favorite things about maintenance manuals is the pictures. If there is any manual that really gives you an idea of what it takes to build an aircraft, this is it! This B-25 manual also has some great perspective and exploded views of the aircraft, three views, station diagrams, and SO much more. Want to read the full manuals without paying to download the entire thing? Consider becoming a member of AirCorps Library! For just $9 per month or $75 per year you can read this manual cover to cover, along with thousands more - not to mention do a deep dive into our 499,000+ warbird engineering drawing archive.

Instruments, Instruments, Instruments!

The 32 new instrument manuals that we added this week include some really interesting product catalogs, which is a bit of a departure from the normal military published manuals that we like to deal in. An example of this is the Kollsman Precision Aircraft Instruments catalog. This manual includes photos of different areas of the Kollsman factory, along with descriptions of the many products that Kollsman produced, altimeters, accelerometers, air speed indicators, clocks, compasses, engine gages, and much more!
