OK I've been bitten before when I thought a trailer was being advertised as a Shasta and I thought it was a lie. But for the life of me I can't find a 61 Shasta on the internet that looks like this one. The shape is just all wrong for a Compact. It's not big enough to be anything else. Those wings do not look like OEM to me.
The only thing that is "Shasta" about this one is the emblem. Perhaps the most authentic part of this one was this (although these are tough to authenticate):
One of mobiltec 's most consistent pieces of advice over time is to put wings on everything. Seems someone was reading his posts. Those wings are completely wrong (scale) for the shape of the trailer, which looks like a cross between a ham and a toaster. The vulture has better wings.
The side window is wrong, as is the door with the windows, the red side marker, and the siding.
Cupboard placements are wrong for the interior layout too. It looks to me like someone's idea of making it more marketable, by attaching a recognizable name to something that most people would never recognize for its original manufacturer.
