Hi, I too am a new member of the forum, so hopefully I have managed to reply correctly with attached photos.
Is this the item that you are looking for?
it’s been well used and may need some minor adjustments to fit your machine correctly. The chrome is in average/ good condition for something that was made back in the 1970s. It is not a concourse item but is a tidy usable item.
I am wanting £35 for it. if you have an interest let me know and I will find out how much it will cost to post to the USA.
Regards Steve
