Sounds like a "good deal" but a gaucho from a 70's trailer is much different than one from a 60's. The mid-70's were not "real wood" the 60's were. Also, I believe Caravels are narrower in width than the larger models and I know the curves are different.
It may be able to be modified to work - but...
