[Sleepy]

Yeah, but Chasey's a dwarf right? and being one of the seven myself, I thought he could be counted on !

Hi.
Portholes with out a makers name on are a bit of a no brainier, they were bought off the shelf in the majority of cases, with foundry's turning them out by the thousand, there was even a firm in Wakefield 80 miles from the sea shipping them to ship builders world wide.

A few of the portholes that have a name on that I have, have the name "George Nemyer, Steinwardle, Hamburg" on them, another ships chandlers (later bombed out) selling boat bits at the turn of the 19th century.

As you say the boilers you can see are a better bet, it is at this point you need Gordon Wadsworth off the Jane R, he can narrow it down by the way the boiler fire hole is constructed, whether it is ribbed, or the size, plus other stuff known only to him!.

The condenser you think you might have seen is quite important as it could be a "Greens Economiser" a patent of Greens Engineering in Wakefield, West Yorks, UK.
This might date the wreck after the patent date (Google search 1928), and the shape might narrow it down even more

Plus! the scrap value alone of the condenser will keep you in drinking vouchers for a good while to come.

Interestingly, my porthole that I got from the same wreck last year only has the single dog, and the one Jay got a few days ago has 2 with the straight wing nut style...... 3 different types of porthole from the same wreck.

Shows how difficult it can be to identify a ship from a porthole that could have been bought off the shelf.
