i used to rebuilt these in the 80,s 90,s as a hobby
they were quite rotten back then
i even used to paint them myself (cellulose back then)
i used to buy them for £500
and sell in that condtion for £2500 - £3000
if only i had saved them all
you have a beautifull looking TR6 there and id love another especially like that one
enjoy
ps i know every nut & bolt on these if you need any info
well done
