Hi All,
Hope you had a great ride today!

(Sorry- I messed up the title. It should say "Not Sure How..." I could not figure out how to edit the title.)

My "Project-O-The-Month" a 1968 Schwinn Pixie. (Knowing me, it will probably be a project of many months)
The steering & fork are quite loose and wobbly, so I'd like to remove the fork and related components for inspection and repair.
The handle bar plus its quill and stem are all one piece of tubing.

But, I'm a bit confused. I thought I had better ask you all before I wreck something.

I don't see the usual jamb and cone nuts to loosen & remove the stem and fork.
In the attached photos, you can see a chrome escutcheon that I think is covering the jamb and cone nuts. It is at the top of the headtube where the handlebar stem enters the tube.

In that escutcheon is what looks like a pin. However, there is no hole on the opposite side to drive the 'pin' through.
My second guess was that the escutcheon is threaded onto a hidden fastener.
I did not try to un-thread the escutcheon with a leather strap wrench. (Deciding instead to ask the experts first...)

So, my final guess is that the 'pin' is in reality a rusted-in-place threaded bolt or screw holding the escutcheon on and that someone snapped it off in days gone by.
Please tell me I'm wrong! (Screw extractors & I don't often play well together when the fastener is this small.)

Assuming it is a screw and I remove it and lift the cap up, will I find the jamb nut and cone nut below and be able to remove the fork & handlebars?

Thanks For Your Advice! It's much appreciated.
Paul
