Museum of Computing arcade machine borrowing request

Hello,
 
We run the UK's first dedicated (physical -not online) digital history
museum which is situated in Swindon, namely, the Museum of Computing.
Most of our exhibits consist of home computers of the 1970s and 1980s
but in January we will be launching a classic electronic games
exhibition . We are very keen to attract sponsors who will be given
return advertising and credit. In this respect, we would very much
like to display an original arcade machine (stand up or cocktail
table) as a temporary exhibit and wanted to ask whether anyone/any
company would be prepared to loan a suitable exhibit for this purpose?
 
We are a non-profit museum seeking to preserve digital history and
educate, inform and entertain those who may be interested.
 
I would be happy to liaise further to provide more information,
especially how we can promote your business in return for any
financial/non-financial assistance.
