With the referral from another member I contacted Stephen Hull, UK. With 72 views but no replies I thought it would be of interest to post Stephen's email to me which I found informative:
Dear Innes
Many thanks for your email and enquiry.
You're quite right that there were two distinct Minor models, announced at the same time as the beautiful Onoto Magna in August 1937:
- 1201 - straight cap with one band and short, stubby inner cap, with Warranted 14ct 22 TDLR & Co Ltd nib - retail 7/6
- 1202 - streamline cap with two bands, longer streamline inner cap, with Warranted 14ct 33 TDLR & Co Ltd nib - retail 10/6
Both models:
- have a teardrop RG clip, sometimes with 'sunburst' logo, instead of 7-sided TDLR logo. [I've yet to ascertain why the difference, which also applies to some other Onoto models)
- were available in black, blue, green, silver and golden brown in a 'new patented all-over ink visible window pattern'.
- have a unique plunger-filling system, different, so I'm told by my pen repair friends (and apparently easier to restore), from the standard Onotos in the construction of the plunger-filling rod and piston assemblies.
- had matching pencils (plain and band) at retail 5/-.
- were probably withdrawn early 1939
Also note that there was a 'wartime' Minor, announced in November 1939 - 1200, same as 1201 but with smaller nib , in chased black with no ink visiblity, retail 7/6.
Kind regards
