So I was just cleaning up a Mk.1 blade holder and noticed some interesting differences below the blade support washer (9-003). There was some nice original paint remaining below the washer - almost an exact match for Deep Brunswick Green on the blade carrier, but on the washer it was much paler and very close to Mid Brunswick Green. The blade assembly came off a Model 2 in the 17,000's with a model 1 style base.
Was there a change of colour on the Rotomos from Mid to Deep green around this serial number?
Also, is there any issue putting a Mk.1 assembly on a Model 2 base (clearances etc)?
