Thank you all for your comments.
Atlantia, the ancient technological 'rollers' work a treat
This 'beasty' was down in a household cellar....and was a logistic nightmare to get out, a 'counter balanced hoist', make-shift supports and alot of grunting ...eventually 'eased' the anvil through a small window
Ah, the neighbours, fortunately they are used to my 'eccentricities'....but I will have to 'limit' the noise pollution : ....well I'll try

Apparently attaching large magnets (either end) and placing heavy chain around its 'waist' helps to greatly reduce vibration.
My forge is 'under construction', I'm using a cast iron BBQ which I will line with refractory, a steel pipe will be fitted (drilled) to direct air. I have already got a little compressor to provide the 'blow'. I have already started to search 'boot fairs' and already have a number of hammers, files etc (all dirt cheap

)
Hi A G Maisey,
this anvil is around 250kgs ( 519 lbs) in weight

the largest I have found in this pattern, so far, is actually smaller than mine.
The anvil's manufacturer is 'Peter Wright' , so the anvil is circa 1860....I do not know when they ceased trading. It also seems that 'Peter Wright' produced quality anvils that are still covetted today. (I found a web site dated 2003 that was offering a 350lbs version for $1400

) It has a lovely 'ring' and rebound. I was going to mount it on railway sleepers. I dont think I will be able to sink the base 3 foot though, I think it will be a case of trail and error getting the platform and sound deadening 'measures' sorted. Have you ever posted any of your work ? I would love to see a few pictures
Kind Regards David
