Are my guitars nitro finished?

[wrxplayer]

Thanks in advance for your input.

I have three MIJ guitars for sale, an '80 Greco SE600, an '87 Greco Mint collection SG, and an 80's Burny FB90 firebird. More info here: http://tokaiforum.com/viewtopic.php?t=17512&sid=034d364a5f7c37712fe39d6d3ed3e777

I've been asked by a couple prospective purchasers whether they're nitro finished and I don't know. Do you?

I would think that all three would be poly finished, do a search for 'acetone' on the forum this will provide some advice on how to test to see if they are nitro.
