A very well-known Feldrock, and the centre piece of my collection, the Riesenflugzeugabteilung 501 (Giant Aircraft Detachment 501) Sergeant's Model 1910 Flieger tunic. The tunic correctly adheres to the regulations for Fliegertruppen with single Garde Litzen on the collar and double Garde Litzen on the cuffs.
Next, the Canadians. This is the Maternity tunic of 2Lt George Hughey from Kamloops BC. The tunic is a fine quality twill with cloth embroidered rank pips and RFC wing with a Toronto tailors label. 2Lt Hughey's RFC records indicate that in Sept 1918 he was trained as a Camel Pilot.
Below, a Maternity tunic of an RFC Observer. Note that this example has "lancer" cuffs and bronze RFC collar badges. Sadly, the tailors label and name tag have been removed, most likely when the family who owned the tunic sold it.
I'll close the Maternity tunics with a rare one: Model 1914 Royal Flying Corps Other Ranks issued Maternity tunic. The Model 1914 differed from the Model 1912, in that it carried shoulder straps, a closed collar, an angled front opening, plain cuffs, and pocket flaps.
And my only American, an RFC Lt cuff ranked service tunic. This tunic appears to have been made for an American Volunteer with the RFC. The tunic has RFC brass collar badges, RFC buttons and embroidered RFC wing with no evidence of any other previous insignia. The ribbon bar ribbons are for the U.S Mexican Border Service, British War Medal 1914-1920 and the Allied Victory Medal ribbons which indicate an American who volunteered for the Royal Flying Corps. The tunic has wear and repairs consistent with flight service and has two brass wound bars on the left sleeve. Unfortunately the tunic is not named.
