Good evening all,

Has anyone fitted a Myford type milling attachment to a Mk1 Bantam? If so, I'd really appreciate some photos and hints on "how to".

When you say 'Myford type milling attachment', do you mean a simple vertical slide or more like a Rodney?

If a generic vertical slide, a simple adaptor plate that bolts onto the cross slide using some of the many tapped holes Colchester provide (UNC threads) and having fixing provision for whatever design of vertical slide on its top face would do well.

If a genuine Myford, perhaps a Myford cross slide from a breaker could be thinned down and drilled to suit.

I made a Tee slotted table a long time ago for a Bantam, it used the 4 tapped holes that are designed for the rear tool post mounting plate and did not affect the top slide use. It was made from a 1" thick cast iron slab.
I used it to hold down a cylinder to line bore, some years later sold it on.

If you join the Colchester iO Group you can check in the Photo section for the fully dimensioned drawing.
