help dating Harry Quinn frame?

HQDP · Mar 27, 2011

This is my trusty Harry Quinn, bought it second hand around 1995.
Ishiwata 017 tubing, frame number Q1064

Currently set up as fixed (not many hills around here), originally came with eclectic mix of parts: 3ttt bars&sttem, campag hubs and rims, suntour (12-speed friction) deraillers and brakes, sugino cranks.

Any ideas as to it's age?

Apologies for dirtiness: no time to polish her up...

Thanks!

I'm reading that as XXX54.

Nice bike.

it seems... Q1054 to my eyes...

HQDP · Mar 27, 2011

yeah, the photo is pretty misleading.
it's definitely xxx64

He used a "0" and "1" to make a "Q"
it's not clear to me if did the same thing with a "D" (to make QD64) or if the 1 and 0 are just rather close (for Q1064 - a more "normal" Harry Quinn number if I understand correctly...)

Thanks for your input!
Cheers.

I don't know how to date a Quinn from the serial number, but I think the Ishiwata tubing would place it in the early-mid eighties.

It's good stuff: 017 means 17 thousands of an inch:

The Cyclone brakes appear in the 1984 catalogue:

Sheldon's quoting Andrew Muzi, who knows far more about bicycles than I ever will, but that information is contradicted by Ishiwata's own catalogue:

An 017 11-tube set weighs 1855g and builds into a 2130g 54cm square frame.

I managed work out manufacturing date of various components that came with the bike, thanks to
http://www.vintage-trek.com/component_dates.htm
rear/front suntour derailleurs: 1986/84
sugino cranks 1985
so spot on with the mid-80s suggestion!

Thanks!

Mid/Late 80's was going to be my suggestion as well with it having the 017 tubing. With the number in the '1000's' it could be a South Wales built HQ especially as the badge says 'Great Britain'. I believe that Frank Clements era HQ's said 'England' whereas 'proper' HQ's from Liverpool had the Walton Rd address. When did the great man start building again in South Wales?
