Thanks folks got my answer and a few more , the reason i wanted this is i am looking for anvils on ebay still and people haven't got a clue they think the word "heavy" covers it , last time i turned up to see an anvil in my tiny little car it was over 500 lb !!! and was strapped to a JCB front arm to move it lol
this is a classic example of an anvil for sale in the uk http://www.ebay.co.uk/itm/Old-English-Traditional-Vintage-Blacksmiths-Anvil-on-Stand-with-Stakes-USED-/221277041275
even company,s selling them are to lazy to find out how heavy they are.
My current anvil is 544 lb and is a nightmare to move even inches its an ISSAC HILL from 1835-1850 and came from a lunatic asylum in Bridgend South Wales its a great story but unfortunately i may have to sell it and move to a smaller one just to get some cash to pay for my collage course...i start Monday (gulp )
