if you have the manuals i would appreciate them thank you
Singermachines is great, they have lots of the manuals on their site for free download
The ISMACS site is fab for
serial nos on Singers, theres a great model description and a decals identifying page too.
If you need a one off part,
Helen Howes site is worth a looksee too
Tools For Self Reliance do indeed collect machines (and lots of other tools) to refurb and send out to Africa. HOWEVER please
DO NOT GIFT THEM A BULLET/FLYING SHUTTLE MACHINE!!!! They can only take the round bobbin ones and the rest get tipped- I sheet you not, the local collecters round here didn't even bother weighing them in for scrap, they were just tipped. It's a brilliant charity but the amount of beautiful old machines that have been junked is a complete crime. Here's a
list and ident guide to ones they DO send and theres contact numbers for the charity on their website too
I'm loving the Jones machines most at the moment... they're not Singers, but they're a solid and vastly unvalued English machine. You got some cooooool machines, guys

Thanks for sharing, I can't believe I've not stumbled across this thread before!
You can buy the treadle belts on a roll, tis much cheaper than someone else cutting you 72" off their roll

They're readily available on the Bay and other places, our Leicester sewing machine shops all keep a roll for the outworkers.
