Harley model J board track racer. Plate info not paticularly helpful: FR 3030 ✗ Untaxed Tax due: 01 March 1992 MOT No details held by DVLA Vehicle make: HARLEY-DAVIDSON Date of first registration: August 1984 Cylinder capacity (cc): 1000 cc Fuel type: PETROL Export marker: No Vehicle status: Not taxed Vehicle colour: GREEN Vehicle type approval: Not available Wheelplan: 2 WHEEL Blackpool plate, I think issued in 1921. Likely to have a Swallow connection somehow - maybe it got a sidecar later???!!?? http://www.jaguarheritage.com/t/history_1920 As you can see, it was Lyons on the Harley-Davidson. There is one error in the accompanying blurb, the Austin Seven was introduced in 1922, not 1927. I don't think the bike has anything to do with Swallow, according to the German Wiki page, Lyons was a keen motorcycle racer as a young-un, unlikely he'd bolt a chair onto a race bike with no front brake.....
The picture was apparently taken before the formation of Swallow in 1922.

The Lost Battalion
On the right is a Harley-Davidson and on the left an Indian. The Indian looks to be a side valve model so is probably a Scout from the 1920s. The Harley could be closer to the correct period. I will check.
The Harley has electric lights so is a Model J - like this one http://motorbike-search-engine.co.uk/classic_bikes/harley_davidson_11j.jpg but could be anywhere from 1915 to about 1924.

Indian circa 1920 ?? http://www.findthebesthere.com/classics1.htm Very nice link! There I found this Harley-Davidson: http://www.findthebesthere.com/bike173061504.jpg It has the same overhead valves that protrude into the tank. What do you say? BTW, where is Jun? your suggestion is better than mine and I do think you are right - I quit too soon . On s'approche, on s'approche... http://indian.harley.free.fr/datas/photos/harley.jpg mais c'est pas encore ça: transmission à courroie et réservoir entre-tubes...
It's Harley-Davidson. This front fender was used from 1921 to 24. I think it's small (61cu in) Harley-Davidson model J (1921-24) same year (but big 74 cu in) model http://www.biker.ru/articles/walkka/fin05.jpg

The bike on the right is a BSA - a side valve single from the late '30s - although it appears to have been fitted with later model telescopic forks. Don't know the model code yet. The bike on the left looks like an Indian Chief - maybe early to mid '30s.
I think its a mid-late twenties Harley Davidson J or JDH. http://www.motorbike-search-engine.co.uk/classic_bikes/harley_classic.html Indians never had those huge cut aways in the tanks but Harleys did.
