Topic: 2 very strange unknown objects

I only purchased these recently to load onto this site to see if anyone can ID them, not my cuppa tea.  Not something I have ever seen before so absolutely no starting point in my search.  They are both pretty solid glass therefore quite heavy.  They both appear to be marked on the base, the square one is not clear and the letters H & W appear with the number 58C (or0 ).  I am hoping this is gonna be a real challenge to someone other than me

here is the other one

Hi there:
I am guessing that they are (might be) Glass Blocks that one builds into houses.  http://www.advantageglassblock.com/  That would be my guess...now they might be older ones

[dinklepip]

mmmmmmmm that's something I never thought of.  They are slightly yellowed so I am assuming they have some age to them

[meegs]

electrical insulators?

The top one looks like it's a pavement light with the raised grid for shoe grip.  You need Ian Macky for ID...and try a search on here for 'pavement lights'.   :thup:

I agree with Max. I've dropped Ian a note to ask him to take a looksee.

The first thing I thought of on the second one was a light lens or cover.  Marine?  Industrial?  On what I have no idea.

oh this is great, it's keeping ya'll guessing heheheh

100% sure these are vault lights ("pavement lights" for the Brits), but don't know who H&W is.  Are you positive that's the embossing?  The "H" is clear enough in your pic, but I can't make out the rest.  "58C" is like a Hayward Brothers (& Eckstein) style number, but these pattern lenses are not listed in their ca1900 catalogue (I see lense numbers like "53C" and "51G" there).

Haven't seen these exact patterns before-- the round one is a fairly common shape in general, but not with the raised grid on top (to make them grippier for shoes-- otherwise they are Slippery When Wet).  The square one is a style that's designed to have as much glass exposed on the bottom of the panel as possible-- hopefully all glass-- the better to transmit more light.

Do you like insulators?  Trade you!!!
