Hello VTT - New Member - 61 or 62 Shasta Compact

The MHMA tag would not contain the VIN number, only just the codes for the build at the time of the build. Shasta trailers had the VIN located in two places on the tongue. On the curbside, that is the side where the door is, it is stamped on the outside rail of the tongue. There is also a plate welded inside the streetside rail that contains the VIN also. Of course now that I need it I can't find the handy dandy "Shasta VIN locations" diagram....
In most cases the numbers are obscured from years of weather, rust, and coats of paint. It will take some effort to make the numbers appear. They will usually surface for you if you use a wire cup brush in your drill or scrub the area with a stiff brush. Don't use anything as aggressive as a grinder though, as the stamps can be obliterated rather easily.

The VIN should be a set of numbers preceded by a letter. The letter is the code for the manufacturing plant. The numbers were set sequentially at each of the plants, and really do not contain any hard information with regards to model or year built. The age can be deduced from the VIN by comparing to lists of other VIN numbers collected.

The # on the MHMA starts with the letter "T" and followed by three zeros and a 4-digit number.  I used a palm sander on the weekend to take off some flaky rust particles and did some inside where this plate is supposed to be welded but there is no plate there.  I only lightly sanded the outside part of the tongue rail and there is nothing there that looks like anything was etched on the outside.  Thanks for your help and if you find the diagram eventually, I would appreciate looking at it.
