Drop Outs - Who makes them and where to buy?

[JoeH]

I'm looking for rear long slot dropouts, e.g. Campagnolo 1010

Who else makes drop outs?

Does anyone have any? or know a good place to buy?

Context is a friend who is a keen hobbyist frame builder, is restoring a frame for me (an old Claud Butler). We wanted to find some modernish dropouts. i.e. have a gear hanger; screws for squaring; thick enough for qr; possibly mud guard eyelets; and to fit a 70/71 degree angle.

Ceeway used to be well-regarded and it seems that they cater for small orders https://www.ceeway.com/NEWPARTSPAGES/Forged Dropouts.htm

I've got a bucket of eyeleted dropouts, but no campag iirc

@bikeworkshop I think he means a similar design to Campagnolo 1010, not neccessarily that brand.

I'll dig out the bucket.
There usedto be loads of half decent bikes with a cracked dropout.
Some frames were prone to it, but a lot of bikes had had a 130 or 135 wheel bolted into a 126 dropout then ridden for years
Unfortunately it's quite a bit of time to replace both Dropouts, even with a frame jig, and those old stays got a bit grainy if you poured in too much heat

How do I know whether a drop out is 70/71 degree or not?

I've got quite a shortlist from ebay so far, seems to be a battle between Ceeway, Campag, Shimano and Gipiemme:

The length of the tabs is crucial to what's already on there.
The actual dropout angle will depend on the insertion into the stays. If you're not building from scratch, your options are limited.

Dropout bucket located.
A history of poor building maintenance by the landlord can be seen in the "finish"

Is this how to measure the angle, something around low 70degrees: 70/71 degrees
