All right!
Saving old stuff is where knowledge begins.
Now, what's interesting is the ratios among the Andorra prices.
For example your 2859 is roughly worth 16/20 = 4/5 of my 2860 (that is: when mine would be in the same fine condition as yours, and mine has a top repair, replaced tuners and the frets are unbeveled at the moment.
What is also interesting is the price ratio between for instance the jazz box 2355 and the 2860, which was roughly 1:1 !!!
Other new info on the list: there was a 2355, a 2355M but also a 2355 DX.
That's something that actually belongs in the jazz box pages of course, but it is important information. Now we know that we must try to find the "DeLuxe" features of the DX. And we know that the value of the DX is higher than that of the standard and lower than that of the M(aple).
What I find interesting is that the 2860 is on the 1977 list. The list of 1976 only mentions the 2862.
It is also interesting to see the prices of classical Cimar guitars, which are much lower.
In Holland they are pushing these old Cimars and asking pretty high prices. I was thinking perhaps a little too high. If I remember it well between 300 and 400 euros for a model with nice inlays (sold).
And now there is a 379 for sale on the "marktplaats" for 235 euros. I can't find it on your list. It seems to have a solid spruce top and an ebony fretboard.
I'm pretty sure that it's not the level of our guitars. (Then it would have carried another label)
