Kona Lava Dome 88/89

[elephant]

Hi, I have a kona lava dome from 89/90, it has a 19"steel frame TBG in Kona Purple, designed by 'Joe murray' (sticker on top tube) it has the original Shimana Exage LS 500 components and still has the original Maximum reaction tyres, velocity stem, P2 forks, Kona Avocet saddle (everything is original other than the grips. I have had the bike from new and it is in excellent condition, All the stickers are intact. I have just had it serviced and all that was needed were the gears adjusting.
Can anyone give me a figure as to how much it would be worth

If you have an account then one way to get an idea is to see what they have been sold for on ebay.

Am not sure how significant the year of manufacture is, for all years there have been half a dozen examples ranging from £53 to £250 sold during the last two weeks, so perhaps you could compare the spec/condition of yours to what have been sold to narrow it down?
