Mystery frame ID please

Hi - can anyone help identify the old frame that I acquired? It's been built up and is a bitsa. On the underside of the bottom bracket I can make out "EO" in a triangle and "234". The rear forks have Campagnolo ends. I really like the cut-out heart in the lugs. Does anybody know the brand of the frame? Grateful for any info or ideas. Thanks.

Reminds me of a 'Clements' Claud Butler

Looks like a 'generic' 1960's/early 70's frame with standard Prugnat lugs that could have been made by any one of many builders, especially if it came from the London area. There were quite a few frame builders who worked for 'the trade' and supplied lots of shops around and about with 'blank' frames ready for the shops to brand as their own. The seat stays however are a bit 'chunky' which possibly points toward a road racing design. Isn't the EO 234 the make of BB shell?

If the Reynolds labels (with "Ti") are original, the cycle is 1977-mid 1980s.

Those chunky stay tops and lugs look like my Witcomb.
