I recently bought this anvil and someone I see here has helped with some info about it ( many thanks ) but I thought I would post the details here too in case I can find out a bit more.
it has only 2 marks on it as far as I can see, both like an upside down T, one of them has the upright going to a point.
it is probably made in england, is quite old and is very roughly made.
the flat part on top is infact convex across the width and the edges are rough rather than straight and square.
I did not want to grind them square just yet but will try it as it is at first.
it is 21 1/2" long, 9 1/2" tall and the top is 3 3/4" wide
weight is 99.4 lbs 45.1 kg
handling holes etc
two holes in the front, one near the base and the other half way up
one half way up the rear, all of those about 3/4 square and the larger one in the base with quite a taper.
top is not delaminating or detempered as far as I can tell.
apart from the hole in the base the base is reasonably flat though I have not put a straight edge across it but the top of the anvil is definatly convex, mostly at the front ( I would say about 3/16 higher in the middle than the edges at the front end and just about flat near the hardy.
have some more pix to post soon.
the casting has a very rough surface ( worn smoother with age but still uneven ), like it was moulded in clay using your hands only.
the hardy hole is not square to the centerline of the anvil but is twisted at least 5 degrees anticlockwise IIRC.
the pritchel is 1/2" diameter
I like it and will use it, in fact it will probably be in use this weekend as I have some small items to make that I dont need the quarter ton monsters in the workshop for ( that are much to high for me as the owner of them is over 6' tall )
