Here is my latest addition. It is a VERY low Serial Number (4942) Rockford 18s Model 1 KW/KS 9Jewel marked EXTRA with a Hurds Patent Micro Regulator. It is housed in a coin silver case. Hands are incorrect, but thanks to Marty a correct set is on the way. Special thanks to Bila for explaing the significance of EXTRA on the movement

Cool!

Are you guys sure it's 9 jewels and not 11 in pairs?

I thought the 9 jewel ones were on the 3rd and 4th instead of the pallet and escape? Just curious. Thanks for any consideration.

That is what is meant by 'Extra' on the 9j movements. Rockford merely moved the jewels from the 3rd and 4th positions to the escape and pallet. The 'Extra' movements having 11 and 13j are the ones with pairs on the escape and pallet.

James, you also have a movement with a windowed balance cock which is not that common.

Thank you Darrah!

Of course, I was staring at the jewels and completely missed the barrel bridge marked 9 jewels. Call it brain damage. I'm glad I asked though, learned something new!

Thanks to Bila and Darragh I am learning to sort the treasures from the trash on fleabay from guys like you. Not a bad deal for $175.00 considering the upgrades and low serial number. Cant wait to attend the Horoligical Happenings zoom meeting next week to expand on what I have already learned. Thank You, James
