Yet Another Ernie Clements Frame

Hi Guys. Not a regular poster here but been lurking for some time.

I've recently acquired a Clements frame and could do with a little expertise.

We've identified the lugs as Prugnat (or good reproduction), the tubing is Tange No.2 butted and the rear has vertical dropouts. What's baking my noodle is the downtube bosses.

Normally they are square with M5 thread



These are circular with a square extension forward in line with the downtube



Has anyone got any ideas which levers I can use? Nothing I've got fits, Campag, RSX, 6400,1056, Miche, Suntour Powershift, even some nondescript Huret from the 70s and Simplex.

I'm a bit snookered. Especially given the bosses aren't M5 thread, either . . .

I've emailed the Clements shop, has anyone any other suggestions? Over to you.

I've just been informed that these bosses are exclusive to Shimano AX and use a 4.5mm thread.

I'd appreciate any other wisdom . . .

iirc this was Shimano's attempt to break the campag style stranglehold and lasted about 2 years.

That frame is nothing like any Ernie Clements frame I have come across before. Looks classy from what I can see from the fork crown

Ernie had lots of frames in his ledbury shop he imported some simoncini frames. could be he badged some with clements.

Ah, I wonder if the BB is Italian. Some more pics would be nice

Shaun

More pics as and when ICBA to take them. BB is most definitely English.

Meanwhile, the pic from the bay . . .



Frame number begins M21 if that's any use to anyone.

. . .and some detail of the headtube & fork crown.

paint scheme is identical to mine.. mines all tange champion 1 tubing etc.

Just a thought here....
I agree with Carlrh. Clements were (are still?) UK agents for Simoncini. This could possibly be one of Simoncinis frames 'badged' as a Clements.
But the 'Made in England' headbadge/decal looks 'casual' (if not misleading) if it is.

I wouldn't count on any quick response from the current Ledbury operation.
Simoncini is in retirement mode currently, as is Clements seemingly.
