Do you have the steel points plate or the brass one? There are considerable differences.

Thanks, bsa-bill.

Tumbleweed, since a picture paints a thousand words:-

Steel on the left; brass on the right.

In the steel assembly, the larger boss on the double nylon washer goes underneath and into the central hole in the back-plate. The smaller boss is on top and goes into the larger hole in the spring anchor bracket. The single insulating washer goes immediately on top of the spring anchor bracket, under the metal washer on the clamping screw. (If one of our EasyCap condensers is fitted, it's the single insulating washer that gets replaced by the EasyCap.)

Hope that helps.

Haven't forgotten your offer to test my Maggie Ken, just still toiling with Kitchen and staircase refurb, Kitchens done, starting the stairs when  I get bits and pieces of missing plaster sorted, removed some packing between stair plate and wall and found it to be a rolled up May to June 1963 edition of the Reveille !!!!!!

No BSA adverts that I could see (back on topic)
