I wanted to know if anyone knows what font is used on Big Ben, and if there is a free version I can use or something with a similar feel?http://commons.wikimedia.org/wiki/Big_Ben

Blackletter Iron work was probably a one-off... not a typeface.

That said - there are a bunch here that could probably get you close. http://www.fontspace.com/category/blackletter

Thanks for the suggestions, I made three symbols by hand in flash, they are not perfectly the same but close enough to give same feeling, and anyway did not want to recreate exactly.
