Owners of 99k + bentwood case
 

Please can you show me how the extension table fits inside the cover?

I believe the extension table is an ( add on) does not fit in the case. I do not have the extension table with my 1956 (99K) with bentwood case.

Hmm, I have to take pictures when I get home, but on mine it's simple; there is a black metal bit on the extension table, it fits in a metal part in the lid, and there's a tiny lever you turn in place to secure it. The extension goes in with the top side towards the side of the bent wood cover. My 99K dates to 1934, I think it differ slighly to the earlier version I've seen, where the placement of the knee lever and loose parts are organised a bit differently. Mine is very similar to this 201.

Most of the cases sold in the US did not come with the extension, while they were more common in the UK - sort of like handcranks, way harder to find in the US. If I ever come across a case with the extension, I'll be grabbing it!

AllI have to say to you, OP, is formosa.

I have to say I'm with Cathy. I want one.

Sorry, I’m not following.

My extension came with the machine in the suitcase type of case which got damaged in transit, I went on eBay and purchased a bentwood case.

Aquilegia is the genus of the columbine flowers, and the species formosa is my favorite. I'm a botanist and thought you were one, too. Now I'm curious about your nom de screen.
