Stopped by the DAV thrift shop today and there was an old, I presume< gas furnace there. It looked a lot like the Clayton and Lambert furnaces I've heard guys talk about on here before. No markings left and rusty, but it seemed like it could be made to work again. The "plunger" like what a white gas Coleman stove has to pump air in it was bad, the stem came out and there wasn't anything on the end of it to compress any air.
Are parts available for these? They only wanted $19.95 for it, seems like it would be really useful if it could be gotten working easily. I should have taken some pictures of it, sorry.
