Description

NOTE: I will beat anyone's shipped price on Ebay for this item as I have for the last 15 years!
Always the best price!
This Small ORIGINAL Bristol Spline Wrench set SS-508, is our most popular set for working on Collins Radio Gear, and other electronic gear that uses the Bristol Spline set screws.
They are also used in Aviation gear.

Good Communication and Customer satisfaction is always our number one concern.
If you do purchase an ebay item from me and for some reason are not satisfied or have questions, PLEASE contact me right away and I will take care of it to your satisfaction, (rather than leaving negative or neutral feedback before I am made aware of a problem). I sell hundreds of pieces of used and new gear and it is possible I could miss something or make an occasional mistake, but I will always work to make sure you will be satisfied or I will refund your full payment including the shipping cost, so there is no risk you will be stuck with something that you do not want. I know there are many sellers that do not much care about your satisfaction but I am not one of them! Please consider this before you bid on my items and before leaving any negative or neutral feedback.
