A mysterious braze-on
Picked up an interesting frame yesterday, and it has a braze-on under the downtube and near the shifter mounts that I've never seen before. Builder's error? Flick stand mount? Emergency poker? Any ideas?

My guess a custom.
Only idea that comes to mind is to aid wiring, and that is just a dart toss.

Is there something down near the BB? I know it is an odd place but could it have been a pump peg?

You're very gravity focused today, Bob!
It is a very nicely made frame. I hope to take a bunch of pics after today's ride (on a different bike; this one's not built up yet!). Here's the preview: nicely thinned Nervex Pro lugs, English BB threading and fork steerer, sloping fork crown, takes a 27.0mm seat post, six-digit serial # under the BB, no holes for a badge on the head tube, fastback seat stay treatment, two brake-cable eyelets on top of the top tube, 124mm rear spacing.

At last, here are pics of the complete frame. Any guesses as to manufacturer? Here again are the specs: English BB threading and fork steerer, takes a 27.0mm seat post, Campy dropouts front and rear, frame and fork weigh 6 lbs even, 124mm rear spacing:

warning over-inflation of the front tire. once it exceeds optimal pressure, it's force-exploded. spec-op way, you know...
i mean. beautiful frame, regardless.

Stop reading my posts!
no idea here, either but i suspect this (early) frame was given those WB bosses (and MAYBE the shifter bosses and TT cable guides) later in life.
Very nice Brit frame, probably also got the rear opened up from 120 to 124 (just couldn't go all the way to 126, huh?).
The fork crown is either a Davis or Haden so fork was probably concurrent with the frame, I wonder if the BB shell is a Gargette Bros or that other brand that has similar stamp but different initials, and also if the "72" at end of serial number is the year built...
27 seatpost might indicate a slightly heavier/thicker wall seat tube than the usual 531DB.

Another guess - not seen above: a mount for one of those wire thingies that rub on the tire to knock of debris before they cause a puncture.
I recall seeing very similar bike frames in a shop in Feltham (London suburb) in 1974. Sorry, don't remember the name of the shop, did purchase a Meada (Suntour) gold 5 speed corn cob (14-15-16-17-18) freewheel from them.

I tend to agree since 1974 would have pre-dated the frame having bosses originally. Just something fancier than the little flat triangles I've seen on other frames for the clamp stop.

I like unworthy1's thinking that this may have been a stop for clamp-mounted shifters and the current shifter bosses may have been added later. It's a beautiful frame, and one built with a lot of care. But looking at the junction between the shifter bosses and the down tube, there is a slight gap which does not appear to have same consistent quality of workmanship as the rest of the frame.
