Vintage new old stock Bulgin right angle 3 pin mains plug.  This is not the more common mini version still available today but the full size version with half circular entry or keyway.  

The main body measures close to 40mm tall and wide. The round male part that fits into the panel socket is 21mm wide and the half circular keyway has a diameter of about 8mm.  The pin spacing is about 11mm center to center.  In contrast, the mini version is about 25mm tall and wide. The difference between the two versions is shown in the 3rd and 4th photos.

The matching Bulgin panel socket is SA2096 which I do not have (see last photo, first row).  If you have the SA2096 and are in the US, I would be interested in working something out since I have more than one SA2097.

Please also note that the SA2097 will not fit or work with the much more common Bulgin panel sockets with the square bottom groove as shown in the second row of the last photo.

Auction is for 1 unit only as shown in the first photo.  Any other items pictured in later photos are not included in the auction price and are for information and clarification purposes only.

There is no need to pay for expensive global shipping since first class postage in the continental US is included in the auction price.  For less than the cost of global shipping alone from across the pond, you can have one of these delivered here in the US.  Also, no tariffs on this UK item already here in the US.
