Original Collins Weighted Spinner Knob for S-Line

Description

Here is an original Collins production S-Line style, weighted main tuning, "spinner" knob which will match the factory knobs on all Collins S-Line equipment.
This particular knob is in excellent condition as you can see from the pictures.
It was first introduced as a cure to smooth out the klunky gear-driven tuning mechanism if their 51S-1 receivers.  I believe somewhere in that radio's production, the main tuning knobs were changed from the regular all Bakelite S-Line knob, to this weighted version which has a solid brass skirt that is painted satin black. Many find that it is also useful on the regular S-Line as well.  It uses two set screws which will secure it to any round ¼ inch shaft.
If you have any questions about this item, delivery times, combined shipping,
or, if you have not received the item once it has been paid for, please
contact me directly at pincon at erols dot com.
I usually ship any item the day after receiving the receipt of payment
notice from paypal.  Then, it is in the hands of the delivery service.
The US post office specifies up to 10 days for US delivery of an item shipped
via parcel post.  International air mail can take considerably longer.  So
much so that a tracer cannot even be filed until at least a month after
the ship date.  I have found that recent international air mail shipments
have been taking six weeks or more to arrive.  Even priority mail times have
extended to several weeks.  I didn't earn over 6000 positive feed-backs
by cheating people.  Please keep this in mind if there is any concern about delivery times.
