What Tyoe of Campagnolo Cranckset is This?
Hi All,
I inherited a 1966 bike and it seems to have a Campagnolo crankset on it. on the dustcap it says Campagnolo Patent. However I can not find anything about this type of crankset. Can someone tell if this is a Patent and if so how do I disassemble it? Non of the tools I have seem to be able to reach the bolt. The same bolt is on the left side as well (if that helps.)
Any help is greatly appreciated.

Welcome to BF. A 1966 bike you say? Photos of the bike would be nice and particularly one of the entire crank from the drive side. Are there any markings on the back of the crank arms?
Also try a thread such as the following to get a feel for what is involved in crank removal:

You need a 15mm socket...probably a thin-walled one. Or a peanut butter wrench.

The tools you require are this one: Crank Puller for Square Taper Cranks - Park Tool
and this one: https://www.purefixcycles.com/produc...m-combo-wrench
Do not try to remove the cranks without both of these tools. Also, show us some more pix. Just the tantalizing glimpse of some fancy lugwork behind that crank tells me that this might be a very nice bike.

Cobra tools still make a copy of / alternative to the old "peanut butter" wrench (Art D-008.15) ... the originals go for a small fortune these days.

Davester is right, you need the correct remover but also make sure that you use it correctly - especially, pay attention to removing the crank bolt washers under the heads of the bolts and when screwing the remover into the crank, make sure that it goes in dead straight and when all the way home, nip it with a spanner.
If the cranks look to have been in place for a long time, thorough irrigation of the crank / axle join with boiling water is a good idea - don't heat with anything else, though. The different rates of crank / axle expansion may help you to "pull" the crank which "might" be very tight.
If you can't shift the crank with a normal, say, 20cm long spanner on the extractor DO NOT reach for an extension bar ... seek help from someone with experience in removing seized-on square taper cranks, or there is a good chance it'll end in tears - we do renovations on 70s and 80s built-bikes all the time and speak from our customers' experience!
If you are in the UK and need any assistance, please feel free to PM me ...
