0 Grade Lifter 10b 2 barrel set - missing a forend?

[Fishrising (Ben)]

I have an 1877 0 grade lifter 10b s/n:9472 that came from the factory with a 32” barrel. At some point it had a 2nd 28” barrel made for it. Both barrels have the 9472 serial numbers on them.

Would it normally have come with a new 2nd forend as well? As the 32” barrel’s forend will not work with the 28” barrels. I unfortunately don’t have a 2nd forend for the 28” barrels. Both barrels lock up tight without the forend.

What are my options? Have a new forend made to fit out of an abandoned forend? Have a new forend made from scratch? Can the “lug” that a forend would attach to on the 28” barrel be cut and re-soldered to the proper place such that the 32” barrel’s forend would then work? Additionally can anyone decipher the notes for the 4 entries of this gun from the Parker log book? Thanks in advance!
