Cover to Ship Upfranked with Danish perfin stamp

This cover was sent in Nov 1975 from Klaksvik to a Danish ship "Maersk Supplier" had an additional 10 ore stamp (with Maersk perfin) applied and postmarked in Copenhagen.

Can anyone explain the need for this? The 2 kr rate also doesn't make sense looking at my Faroe rate tables but this cover looks legit to me...

The current hypothesis is that the high/extra franking was required as the price for a forwarded air mail letter to a new destination outside Denmark (when reposted in Denmark). Ideally there would be a forwarding label to explain the addition of the 10 ore stamp. This is going to take more research...

Bergen Paquebot Handstamps

These are new Paquebot marks used on Faroes mail not listed in Daka GF10 2000. I identified these using Hosking's book "Paquebot Cancellations of the World" (2000 edition):

1915 cover: Figure 623, 1902-1914, scarcity B. The dimensions on mine are about 1 mm wider than in Hosking but this is probably from the heavy impression.
1927 cover: Unlisted in Hosking. 37.5 mm dimensions don't match so this is believed to be a newly discovered paquebot mark. The roller cancel is a standard Bergen roller cancel.
1936 cover: Unlisted in Hosking. 38 mm dimensions don't match so this is believed to be a newly discovered paquebot mark, probably just a heavy inking of the prior cancel in a different color ink. The roller cancel is a standard Bergen roller cancel.
