Trainman2001 posted:TBF was built by Grumman and the TBM was contracted to GM Eastern Aircraft Plant to build. Only minor differences exist that only a model builder would notice. The biggest difference is the full shield between the rear engine area and the engine. On the TBF is just a small disc, whereas on the TBM has a fully-formed streamlined enclosure. In the picture it's that blue shield you see. That piece is not on the TBF. When the cowl is on along with the cowl flaps you won't see this piece. There are some other minor differences which are not as noticeable.
I don't follow airplanes much, but the name Avenger certainly caught my eye. Now I know they were made by two different companies and have minor differences. That adds to my knowledge base. Another coincidence happened when I read an account my uncle wrote about a relative who dictated his experiences on the carrier San Joaquin. Bush Senior was on a sister carrier, so our relative's account added information. Three separate information sources in two weeks about something I knew nothing about prior. Maybe I will remember some of it!
