hi lara
im quite a young man in the world of model engineering and have made many friends through it.
in the past 18 months 3 of my friends have past away and ive helped the widows clear their workshos so i no roughy the value of things etc.
i therefor feel i no what is needed to help you out, as has been said there is alot of crooks out there who will rip you off.
if you werent a millon miles from me (im in shropshire) i would be willing to give you a day or whatever it took to sort out what you have and put a value on it.
you say you have someone intrested in the lathe wel i could tel you the value and what goes with it
im not a dealer in anyway and wouldnt charge to do this just a thankyou and a cup of tea.
if you would like anymore help please send me a email
best wishes jonathan
