A nice plane indeed as a joiner cabinet maker these planes were used lots in furniture making .my passion is for my infill planes which are my daily user planes .
I've had one of these planes since i was an apprentice, think i got in 87. Mine is a later british made version the plastic tote handle and knob Which i have replace with a wooden knob and tote handle which i made from an off cut of a bar top. I was always told they were known as a Wheelwrights plane
I'm a retired Carpenter, I've had an English version of this plane sitting 1978 and I still use it. I always believed it to be called a badger. Bench rebater.
A very nice plane. Cleaned up well. A very good addition to the shop. I have good results using MinWax wipe-on-poly on my wood turning projects. Each coat is thinner than brush or roller, but I get nice even coat. A light hand sanding with 400 grit paper to remove dust nibs, and then buff with a dry buffing wheel between the coats. I apply 4 or 5 coats and get a nice even and hard finish. I am a hobbyist so the time is not an issue. If you want to protect your metal surfaces from moisture, consider Fluid Film. A lanolin based product which works well. UK link to illustrate www.scparts.co.uk/sc_en/warehouse/workshop-fluids-and-consumables/conservation-and-rust-prevention/fluid-film.html Also if you ever want to upgrade a hand plane blade and have the budget, consider a blade made by Ron Hock. He does make a blade for this rabbet plane. www.hocktools.com/products/bp.html I read that Stanley were famous for mixing new feature parts with older stock, so your frog may have been a new design with the micro adjustment screw, but the body may have been the previous design. I have seen this in some planes myself. Dave.
