Morning All,
Quick update(if anyone is interested).
I managed to find the owner of the actuall prop, who bought it during one of the ABC prop sales.
In all the shots from the LOST, guitar seems to be much darker, then on the pictures I got form the owner.
I tried for the past 4-5 weeks to buy and mach different shades of guitar sprays( amber, tobacco,cherry red, wine red,light orange,dark orange,brown, black, etc...) to match the colour, but without seeing the actual prop it is impossible to get the right colour combination and amount of layers(tinted lacquer so the more layers the darker it gets)it is almost impossible, so literally houndreds of dollars later, this is as close I could get. I know it could be a bit darker, but pictures does not reflect 100% the colour I got. I am happy I managed to buy right ANTARES guitar and this is literally all I could do at this moment. Last thing is to create and print guitar sound hole rosette(not my biggest priority right now) and put all the stickers, so it can be ready for next week signing.
